1.  BASIS OF PRESENTATION

   Jos. A. Bank Clothiers, Inc. (the Company) is a nationwide retailer of
   classic men's clothing through conventional retail stores, catalog and
   internet direct marketing and franchises. The consolidated financial
   statements include the accounts of the Company and its wholly-owned
   subsidiaries. All significant intercompany balances and transactions have
   been eliminated in consolidation.

   The results of operations for the interim periods shown in this report are
   not necessarily indicative of results to be expected for the fiscal year. In
   the opinion of management, the information contained herein reflects all
   adjustments necessary to make the results of operations for the interim
   periods a fair statement of such operations. These adjustments are of a
   normal recurring nature.

   Certain notes and other information have been condensed or omitted from the
   interim financial statements presented in this Quarterly Report on Form 10-Q.
   Therefore, these financial statements should be read in conjunction with the
   Company's January 29, 2000 Annual Report on Form 10-K.

2. SIGNIFICANT ACCOUNTING POLICIES

   Inventories are stated at the lower of first-in, first-out, cost or market.
   The Company capitalizes into inventories certain warehousing and delivery
   costs associated with getting its inventory to the point of sale.

   Costs related to mail order catalogs and promotional materials are included
   in prepaid expenses and other current assets. These costs are amortized over
   the expected periods of benefit, not to exceed six months.

   The Company accounts for income taxes in accordance with Statement of
   Financial Accounting Standards No. 109 - Accounting  for Income Taxes (SFAS
   109).  This standard requires, among other things, recognition of future tax
   benefits, measured by enacted tax rates attributable to deductible temporary
   differences between financial statement and income tax basis of assets and
   liabilities and to tax net operating loss carryforwards, to the extent that
   realization of such benefits is more likely than not.

   Reclassifications - Certain reclassifications have been made to the May 1,
   1999 financial statements in order to conform with the April 29, 2000
   presentation.

</TABLE>

   Net current and noncurrent assets/liabilities of discontinued operations
   noted above includes deferred income taxes, pension costs, severance and

7. SUBSEQUENT EVENTS

   Subsequent to the end of the first quarter, the Company canceled a source of
   supply agreement through which 36% of its finished product was purchased in
   fiscal 1999. The Company anticipates no significant disruption to its
   purchase of product.

8. SEGMENT  REPORTING

   The Company has two reportable segments: full line stores and
   catalog/internet direct marketing. While each segment offers a similar mix of
   men's clothing to the retail customer, the full line stores also provide
   alterations.

   The accounting policies of the segments are the same as those described in
   the Company's January 29, 2000 Annual Report on Form 10K. The Company
   evaluates performance of the segments based on "four wall" contribution which
   excludes any allocation of "management company" costs, distribution center
   costs (except order fulfillment costs which are allocated to
   catalog/internet), interest and income taxes. The Company's segments are
   strategic business units that offer similar products to the retail customer
   by two distinctively different methods. In full line stores the typical
   customer travels to the store and purchases men's clothing and/or alterations
   and takes their purchases with them. The catalog/internet direct marketing
   customer receives a catalog in his or her home, office and/or visits our web
   page via the internet and either calls, mails, faxes or places an order on-
   line. The merchandise is then shipped to the customer. The detail segment
   data is presented in the following table:

     corporate office and the distribution center, interest and income taxes.
(c)  Identifiable assets include cash, accounts receivable, inventories, prepaid
     expenses and fixed assets residing in or related to the reportable segment.
     Assets included in Other are primarily fixed assets associated with the
     corporate office and distribution center, deferred tax assets, and
     inventory which has not been assigned to one of the reportable segments.

Item 2. Management's Discussion and Analysis of Results of Operations and
        Financial Condition

The following discussion should be read in conjunction with the attached
condensed consolidated financial statements and notes thereto and with the
Company's audited financial statements and notes thereto for the fiscal year
ended January 29, 2000.

Overview -   Net income for the quarter ended April 29, 2000 increased 129% to
--------
$1.1 million or $.16 per share from $.5 million or $.07 per share for the same
period in the prior year.  The improvement in net income was due primarily to
higher sales and lower marketing costs.

The Company opened two new stores during the first quarter of both fiscal 1999
and 2000 and has 112 stores open as of May 2000.  The Company expects to open
four to six new stores during the remainder of fiscal 2000.

The Company has significant borrowing availability under its current borrowing
arrangements.  The Company's availability under the Credit Agreement was $28
million with $9 million of debt outstanding as of April 29, 2000 compared to
availability of $29.2 million and $7.4 million outstanding at the same time last
year.  The decrease in availability was due primarily to the repurchase of
approximately 13% of the Company's outstanding stock for $3.1 million during the
first quarter and capital expenditures of $5.8 million since April 1999 mostly
offset by cash generated by operations during the same period.

Results of Operations - The following table is derived from the Company's
---------------------
condensed consolidated statements of income and sets forth, for the periods
indicated, the items included in the condensed consolidated statements of
income, expressed as a percentage of net sales.

</TABLE>

Net Sales - Net sales increased 6.4% or $2.8 million to $46.4 million in the
---------
first quarter of fiscal 2000 compared to $43.6 million in 1999.  This increase
was due primarily to a 5.5% increase in comparable store sales and sales in new
stores.  Sales of sportcoats, slacks and sportswear increased to 37% of
merchandise sales compared to 31% in the same period last year while suits
decreased to 36% from 41% last year.  This shift reflects the increased emphasis
on corporate casual business.  Internet sales during the first quarter increased
600% and catalog sales decreased 14% on a planned 10% decrease in circulation.

Gross Profit - Gross profit (sales less cost of goods sold) increased $1.1
------------
million to $23.2 million in the first quarter of 2000 from $22.1 million in
1999.  Gross profit as a percent of sales decreased to 50.1% from 50.7% in 1999.
The increase in gross profit dollars was the result of higher net sales while
the decrease in gross profit percent of sales was due primarily to aggressive
sales promotion in February when we achieved a 20% comparable store sales
increase.

General and Administrative Expenses - General and administrative expenses were
-----------------------------------
$4.8 million in the first quarter of 2000 compared to $4.3 million during the
same period in 1999.  This increase was due primarily to an increase in accrued
incentive compensation expense partially offset by decreases in various other
expenses including professional fees.

Sales and Marketing Expenses - Sales and marketing expenses decreased $.3 to
----------------------------
$16.3 million, or 35.2% of net sales, in the first quarter of fiscal 2000 from
$16.6 million, or 38.1% in the first quarter of 1999.  This decrease was the
result of reduced promotional spending in 2000.

Store Opening Costs - Store opening costs decreased to $13 thousand during the
  -------------------
first quarter from $53 thousand in the prior year.  The Company opened two
factory stores in the first quarter of 2000 for which the Company does not run
an opening advertising campaign which it does for the opening of full line
stores.

Interest Expense - Interest expense decreased slightly in the first quarter
----------------
compared to the prior year due primarily to the lower average outstanding
balance in the current year being partially offset by higher interest rates.

Income Taxes - The first quarter fiscal 2000 effective income tax rate is 39%
------------
which is the same as 1999.

Liquidity and Capital Resources - The Company has significant availability under
-------------------------------
its current borrowing agreement.  At April 29, 2000 the Company had outstanding
borrowings of $9.0 with $28 million of availability under its Credit Agreement
compared to borrowings of $7.4 million and availability of $29.2 million.  The
increase in borrowing and decrease in availability resulted primarily from the
repurchase by the Company of approximately 13% of its then outstanding common
stock for $3.1 million during the first quarter of fiscal 2000.

The following table summarizes the Company's sources and uses of funds as
reflected in the condensed consolidated statements of cash flows:

                                                 =======    =======
</TABLE>

Cash provided by operating activities was primarily from income generated from
operations, an increase in payables partially offset by seasonal increases in
receivables, inventories, prepaids and other assets.  Cash used in investing
activities primarily relates to the purchase and installation of the Company's
new e-commerce website and the opening of two new stores.  Cash used in
financing activities primarily represents the repurchase of common stock
partially offset by borrowings on the revolving portion of the Credit Agreement.
Cash used in discontinued operations was due primarily to the severance payments
and other expenses related to its former manufacturing facility.

The Company expects to spend between $3 and $4 million on capital expenditures
in fiscal 2000, primarily to open between four and eight new stores, to
relocate, downsize or renovate at least two stores and to install a new
e-commerce website to replace its existing site and to install an inventory
planning system. The capital expenditures will be financed through operations,
the Credit Agreement and possibly leasing arrangements.

The Company's Credit Agreement expires in April, 2001 based on its original
term.  The Company expects to obtain extended financing prior to the end of 2000
and does not anticipate any problems obtaining its financing, however, there can
be no assurance that such financing will be obtained on acceptable terms.

The Company's plans and beliefs concerning future operations contained herein
are forward-looking statements within the meaning of the Private Securities
Litigation reform Act of 1995.  Actual results may differ materially from those
forecast due to a variety of factors that can adversely affect the Company's
operating results, liquidity and financial condition such as risks associated
with economic, weather and other factors affecting consumer spending, the
ability of the Company to finance its expansion plans, mix of goods sold,
pricing, availability of lease sites for new stores and other competitive
factors.  These risks should be carefully reviewed before making any investment
decisions.
