Abstract: Each year thousands of millions of items of apparel are purchased. Within a large percentage of these transactions they are undertaken either by those for whom trying the item on prior to purchase is extremely difficult within the retail establishment or where the person they are buying for is absent. It is a common occurrence for additional time, effort and expense to be incurred taking the purchased item back to replace it or have a refund as the item does not fit as intended, by people for themselves or for others who are not present during the selection. Accordingly it would be advantageous to have a simple device to indicate the fit of items of apparel for the individual for whom the items are being purchased. Such a device is presented according to embodiments of the invention.
