Abnormally short sleeves

I bought the medium jacket for my son who is 5'8" and very slim. The jacket fits me. I am almost 5'2" and a size 2 in ladies. Even then, the sleeves come three inches short of my wrist. The jacket looks nice otherwise with lots of pull strings and pockets.. I don't know how waterproof it is since we never wore it out in the rain. I'm returning it.
