This bralette is really great - the lace is beautiful and delicate, but since it's lined with mesh it actually provides a surprising amount of support.  I have been trying to find a bra that's pretty but also supportive and comfortable enough to wear around the house all day... and this is it.  I have found similar bras/bralettes to be useless for my 34C figure - but this really works.  It's obviously not going to provide as much support as a more structured bra, but it's enough!  Also, the seaming on the cups means that it actually creates a nice shape under clothes (unlike some wireless bras that just squash you flat!).  I wear a 34C consistently, and sized up to the Large base on reviews on another site, which fit perfectly.  Highly recommended.
