It’s a combination bra & undershirt/cami. Such a good idea for those of us who are not terribly well endowed! Starting to shop them, I see that some have underwires, so maybe they would also work for women with more. Not sure about that, and there seem to be a wide range of levels of support, but reducing the number of undergarments/amount of hassle sounds like a great idea to me.

Do they sell them in cold parts of N America? I don’t recall seeing them growing up in the Midwest, but I wasn’t in the coldest part.

Those of you in Europe, can you suggest brands to try (or avoid)? Warmth is key, but so is comfort--no itchy stitching--and I'd like to find some that are pretty too.
