Review: Buy these! - I have been on a new bra hunt. Several months ago I decided that the underwire had to go and sort of successfully found some that work-BUT they are still poking me under the arms with a piece of plastic. My husband inadvertently put my underwire bras in the dryer and now all have bent hooks, so it's time for new ones. We have 1 Kohl's store locally and nothing else, so finding a selection is limited. Back to desertcart. I started reading reviews and looking at how many were purchased, etc. I have worn Bali bras before and know that they seem to hold up well and fit me. My only problem with this is the "modesty layer", I am a 40DD and have NEVER had any kind of padding-why do bra companies do this? I don't want or need it. But, in reading the reviews, many talked about how thin this was and especially how comfortable these bras are. So-my thought, "I'll order one and try it and return it if I don't like it". Well, I don't like it, I LOVE it! This is by far the most comfortable bra I have ever worn. It definitely is true to size and I don't mind or notice the "layer". Most importantly, NO POKING, especially under the arms! I can come home and take it off and not have red marks on my body. It is soft, cool, not overly tight (but still supportive) and looks pretty. I love the upper mesh part on these. I do have one comment as several others mentioned, the fabric on the hook part is a little scratchy but only when putting it on. I am a "spinner"-I cannot reach behind me to hook the bra, I have to hook in front and spin around my body (yeah, not good, I know), and it's a little scratchy when doing that, but once on, it's fine. I have now purchased 4 of these in various colors and am hopeful that they will hold up. These are convertible straps (I may never use that feature) and as others have posted, the strap adjustment is in the back. No problem, adjust once and that's fine. I also noticed while trying on non-underwire bras that many had very short straps-I am 5'2" and frequently have to shorten them a lot. Many of the non underwire ones had very short straps that I still had to shorten. These do not, they are more "normal" in length. The price was great too, as the retail is $48 on these (why are bras so ridiculously expensive???). At $23, I feel like I can purchase several. I am QUITE pleased with this and would highly recommend!
Review: Very nice and comfortable underwire bra! - I just received my item today. I lost a lot of weight and went from a 42DD to a 36DD! This bra is perfect in both sizes. It’s soft but gives enough support, especially after things are sagging a little right now! Even with a gentle underwire it is quite a very comfortable bra! Perfect for a T-shirt bra and definitely worth the money!

### ⭐⭐⭐⭐ Thin padding but otherwise great everyday bra
*by N***N on April 17, 2026*

I got a 40B and it's really comfortable and fits well. It was purchased about a year ago and it has become my favorite bra. I like the little gem in front. My only complaint is how thin the padding is. It does not hide the nips when wearing a thin shirt or top, lol.
