Great Fit and Price While Updating My Wardrobe
Color: Shortbread, Size: Large
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. The fabric feels soft and breathable, and it pairs easily with jeans or slacks. Since I’m still losing weight, I didn’t want to overspend on clothes I may size out of soon, and these hit the sweet spot for both quality and affordability.

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.
