This is a wonderful bra for an outrageously low price! It's 100% cotton, very soft and very comfortable. One reviewer commented that "the material in the straps is very rough and the area where the straps meet the inside of the shelf bra portion are not well crafted." I did not find this to be the case in either of the 2 packages (6 bras) that I ordered. The bras were very well constructed and all the seams (a frequent trouble spot) were even and smooth. I'm wondering if that reviewer ordered an incorrect size as a bra that was too small might rub in the strap area. And even though the bra comes in sizes up to 40, I think that someone who was a 38 or 40 would find that this bra does NOT provide enough support. I am a 36B and this bra supports me well during my 12hour day as a nurse on the hospital floor. However, it would NOT be supportive enough as an exercise bra. So, if you want a simple, comfortable bra for everyday use (not exercise)this is a great bra! An added benefit is that it is completely hidden under tank tops:)
