I HATE this bra. I got it for $10 from Amazon, which is why I still have it.
But decided to write about it because if it causes me (firm, shallow and bottom heavy breasts) quadboob it will cause everyone quadboob. I don't wear very tight clothing (and it's COLD here so I wear heavy fabrics), and it was evident even with clothes - I got some strange looks.
The underwires don't even remotely lie flat on me, and the left underwire got displaced.
The wires tend to sit too low under my boobs, and the cup wrinkles on the bottom when I put them where they're supposed to go. Furthermore, the underwire doesn't span the entire cup, and it's much too short on the outside. The outside of the wire pokes my sides which is painful after extended periods of wear. The wire is wider and shallower than it needs to be to fit my boobs.
