“I have to admit I’ve only purchased maybe one new bra since college. I worked as a sales associate for three years at Victoria’s Secret, so during my college years, I not only became well-versed in fit, sizing, and styling but also accumulated a large stockpile of bras that still serves me well. My bra and body size haven’t really changed, and I’m also really picky when it comes to the fit, comfort, and look of a bra. Either I’m going for ultra-comfy and unfussy or I want something beautiful and care less about comfort.

“In terms of my bra size, I don’t have a lot to work with in that area, and I’m pretty much a 32C across all brands and styles I try. Even though the cup size looked bigger on the bra from Wacoal, I was super happy to find that it managed to fit perfectly even without any padding. (For the record, I’m used to wearing bra styles that have at least a teeny bit of somethin’-somethin’.) There was no gapping in the cups, no bunching in the back, and overall, it fit pretty perfectly and lay flat in all the right places. I also appreciated the simplistic style and think bra is the perfect basic (but still pretty) black bra. My only complaint was the comfort factor. To be honest, I found something about the fabric a little itchy—I was very aware that I was wearing a bra—and I even found it a little uncomfortable in the cups, mostly on the sides where the bra hit near my underarms. (But again, that will probably depend on the person and the way your boobs are shaped.) However, I still wore it two days in a row and appreciated the support it offered and the smooth, clean shape it lends under your outfit.”

“I was an instant fan of this bra. Even though the padding is very light, the fit of the bra gave me an almost push-up-like effect—a minor miracle considering I have a very small chest. I also like the deep V, which will make it easy to wear under a lot of different tops and dresses. Finally, I like the delicate lace and classic design.”

“Right off the bat, I realized why this is such a top seller: The material is silky-smooth and breathable, and the straps are on the thicker side, which is always a plus in my book. Usually, with unlined bras, there’s a chance it won’t look as smooth as if it had padding, but that’s definitely not the case here since it’s clearly so well-designed. The only con? I thought that there was oddly too much material in the cups, but maybe it’s just because I’m not used to wearing such a full-coverage style. Either way, I’m thrilled to have this as an (actually cute) everyday bra.”

“I like that this bra has the pretty lace detail on the side but a rather straightforward strap. This one gives great coverage, the fit is flawless, and it has that underwire support that many women want. My only other note is that you may want to store this bra properly to keep the cup material from rippling. After it spent a little time jumbled in my underwear drawer, I had to smooth out some lines that appeared.”

“It has always been a struggle for me to find a strapless bra that actually stays in place, but this one doesn’t fall down, unlike other ones I’ve tried.”

“I cannot say enough great things about this bra. It’s no wonder it’s on our top-sellers list! Not only does it fit beautifully, but it’s also completely invisible under my tops and shirts. When I first put it on, I thought the fabric was a little stiffer than other bras I’ve worn in the past, but once I broke it in, I didn’t notice this at all. I literally wear this nearly every day because it is so comfortable and seamless. Moreover, it’s super pretty! I’ll be purchasing it in black as well.”

“A truly great everyday bra that is super comfortable and supportive even without an underwire.”

“This bra has officially been adopted into my weekly rotation of favorite bras. It is slightly more padded than I usually like, but I often go for cups that are barely lined. It’s just lined enough to stop nipples from making themselves known, and there are definitely some situations where that’s preferred. It does have the support of an underwire, so that inherently makes it a little less comfortable than bras without a wire, but I still found it to be very comfortable. The best part to me is the shape and how seamless it looks under a white T-shirt. It molded to my shape completely so I didn’t have any gapping, which is something I’m no stranger to in bras. It’s definitely now one of my go-to nude bras.”

“Light-as-air, delicate, and extremely pretty! I tend to wear bralettes and very lightly lined bras, so this was the perfect thinly padded bra I’ve been looking for yet still provided enough support and nipple coverage. If you’re needing a bra to wear with sheer tops and fabrics, then this is without a doubt your best choice. Not only is it super soft and comfortable, but it also looks nice and smooth under tops and shirts. I love the nude rose color for its versatility.”
