I went American Apparel in downtown DC last month with my friend Tasha and I was just going to wait on her because they don’t sell plus size. I walked by their 1 size fits all oversized chiffon button ups. I haven’t fit 1 size fits all since I was in high school bahaha. I tried it on because of the oversize part. For plus size it’s not oversize is just a fitted button up. It will go up to a size 20. Mind you I’m a member of the itty bitty so if you have big ones I don’t know how it will work. Check the site they have a nice selection of oversized button ups. If I were you I would only buy a chiffon button color scheme that is not sold at a plus size store. I wouldn’t buy a solid color you can get that at F21, Fashion to Figure, or Lane Bryant.
