I would prefer an item that provides more support and is a bit thicker in order to be useful for BJJ or any other form of physical activity; this does not provide the level of support that serves that purpose in my opinion (and I'm only a B cup). Some padding would be good. Also, it is too low cut to wear on it's own for BJJ in my opinion, although some people might like to show off the assets, I prefer to have the puppies anchored away to get own to business rather than show pony it and worry about stuffing them back in.
Was this a gift?:
Bottom Line No, I would not recommend this to a friend
