Reader C wrote in to recommend this item, which seems like it fills a definite niche:
This cami bra is my new best friend. I have it in white and in black. It is perfect under wrap dresses and the like for work. Some people might prefer the “cami” to come up a little higher, but if I need to be that conservative I’m probably wearing a suit anyway. I had been looking for a product like this for years but the ones at Neiman’s were too lacy and crazy expensive. This one is perfect. No more cutting off perfectly good camis so they bottom line won’t show through. Packing for a trip just got easier too. (How many times have I packed the blouse or dress but forgotten the cami?) Incidentally, at least on me, a 34-D, the support and shaping of the bra is very good and the comfort is fine, though I probably could have done with a DD, which is not available.
Wow! The bra apparently features an underwire, so this is a full-on bra (and not, say, a “dickey” like I remember wearing as a teenager — Amazon has a few lace dickies for sale; they may also be called “modesty panels”) I do like this more modern cami bra, though, and can see how it would be welcomed by a lot of women in the summertime. This one is $32 at Target, and is available in white and black. Assets® by Sara Blakely ® Foundations Cami Bra
