Aritzia only lets you return regular-priced items within 10 days of purchase and otherwise, you\'ll be issued a credit note within 21 days. Since it\'s been a month, they won\'t let you do a refund...

Also, next time if you lose your receipt, they keep a record of your purchases under your account number with them. All you have to do is go there and verify your identity and they can draw up your purchase records.
