| | 1. | I have reviewed this quarterly report on
    Form 10-Q of Aeropostale, Inc.;                                                                                                                                                                                                                                                                      
|
| | 2. | Based on my knowledge, this quarterly report does
    not contain any untrue statement of a material fact or omit to
    state a material fact necessary to make the statements made, in
    light of the circumstances under which such statements were
    made, not misleading with respect to the period covered by this
    quarterly report;
|
| | 3. | Based on my knowledge, the financial statements,
    and other financial information included in this quarterly
    report, fairly present in all material respects the financial
    condition, results of operations and cash flows of the
    registrant as of, and for, the periods presented in this
    quarterly report;                   
|
| | 4. | The registrants other certifying officer
    and I are responsible for establishing and maintaining
    disclosure controls and procedures (as defined in Exchange Act
    Rules 13a-15(e) and 15d-15(e)) for the registrant and we
    have:                                                                                                    



| |     |

| | (a) | designed such disclosure controls and procedures,
    or caused such disclosure controls and procedures to be designed
    under our supervision, to ensure that material information
    relating to the registrant, including its consolidated
    subsidiaries, is made known to us by others within those
    entities, particularly during the period in which this quarterly
    report is being prepared;
|
| | (b) | evaluated the effectiveness of the
    registrants disclosure controls and procedures and

    quarterly report; and                                                                                       
|
| | (c) | disclosed in this quarterly report any change in

    financial reporting.

| | 5. | The registrants other certifying officer
    and I have disclosed, based on our most recent evaluation on
    internal control over financial reporting, to the
    registrants auditors and the audit committee of the
    registrants board of directors (or persons performing the
    equivalent function):



| |     |                                                                                                                                                                                                                                                                                    
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| | (a) | all significant deficiencies and material
    weaknesses in the design or operation of internal controls over
    financial reporting which are reasonably likely to adversely
    affect the registrants ability to record, process,
    summarize and report financial data; and
|
| | (b) | any fraud, whether or not material, that involves
    management or other employees who have a significant role in the
    registrants internal controls.
