Hello, I got a t-shirt which was ordered, the quality is good, but not conform to the description, you have written that it is 100% cotton, but it is not, the material stretches and it seems that there is about 70% polyester or spandex . You have t-shirts 100% cotton? And size: shoulder 40 cm, length 55-60 cm ? Will make a discount on your next order, in exchange for a good review?
