Sizes run small; larger sizes not available
I returned the jacket because the size was much smaller than described. I liked the look and feel of the jacket and the material, but b it x was v much smaller in size than a different jacket I bought at c the same c Times in the c same c size from b a a different company. The other b one for me v perfectly. The Coofandy jacket was not a standard size and much much smaller than I had hoped. If they had offered a larger size I would have exchanged it for a size larger. But they don’t, so I returned it and kept the other one that fit like a glove.

Not for me
The item was too small although I went by the size guide. There is also some uneven white stitching on a gray garment
