I go to different stores for different things. I get shorts at American Eagle; casual and dress button-downs at Express; jeans and random tops at Macy's or Nordstrom; DSW for shoes, especially Sperries👍; then I just get random stuff I like at places like H&M, Lord & Taylor, Men's Wearhouse, or I'll just have an idea for something and try to find it on the Internet. I have to hunt for things sometimes, I'm built too broad for places like Express and H&M, a lot of their stuff is designed for the skinny European look.
All my jeans are from Buckle. They're kinda expensive but they're the only ones I know who have 'curvy fit' jeans that fit my legs and ass :D Plus, it's really good quality jeans. For tops I don't really care. If I like it, I buy it.
