This bra really is too small. However, it's pretty darn stretchy, which means that you can get away with it. It's comfortable, too. It holds your breasts in (since it's so small), but it doesn't pinch or quadriboob them. It's ugly as hell, which means that it's kind of perfect for hard work. All in all, if you desperately need a bra, but don't have the money for something that fits, this is a very good option, and I'd recommend it for that purpose.
I originally bought this bra because it was the largest cup size I could find locally. Since then, I have bought larger cup sized bras online. This bra fits me well (with help). It is comfortable and doesn't poke.
