I shop all over! I've bought at boutiques, department stores, chain stores, discount stores, yard sales, consignment shops, and thrift stores. If it's good quality at an affordable price -- and cute, and CLEAN I'll take it!
I especially like stores like TJ Maxx, Ross, Marshalls and Tuesday Mornings -- where you can find top-of-the-line clothesmakers for less than "big box store" and even, sometimes less than thrift stores! I bought a $119 dress at Ross for $7 -- I've bought brand new clothes at some stores for as little as 35 cents for a shirt!
