As I’ve been getting fitter, my old clothes started looking too baggy, so I needed something that fit better without breaking the bank. This COOFANDY chambray shirt turned out to be exactly what I was looking for—lightweight, wrinkle-resistant, and stylish enough for casual or dressy wear.

I ordered a large twice. 1st delivery was an XL, two sizes too large. The second reorder was an L, and fit like a medium. They can't get the order siz right.
