My best friend's DGD is one of my daughter's best friends, and she does most of her shopping on the sale rack at any store she gets close to! When she was in HS the other kids were sure she got all her clothes from somewhere expensive, but it's just that she knows what looks good on her and never gets the 'cutesie, trendy' stuff so she always looks well dressed. Now that she works at the courthouse (accepts payments at the tax office) she can still wear the clothes she wore at the car dealership and even a few from school.
Sale racks are awesome (but only if they have your size...mine is usually sold out...they don't get many talls especially in larger sizes).
Hope all goes fantastically well with your new job!
