I would definitely not recommend this as a replacement for a bra, but it has perfect bra coverage for sheer or wide-sleeved blouses.  I agree with another reviewer, who said that people who have issues with tight bands on strapless dresses may not find this flattering under thin tops  I have also had some issues with needing to readjust it throughout the night, but nothing too major.

I don't think buying another bandeau brand would solve these problems, so because of the price I would recommend buying this one!
