Update 6/21/23: I wore this bra two times while on vacation this past week. I thought it was super comfortable, gave great lift and shape, and was barely noticeable. I wasn’t adjusting it constantly and I didn’t feel like my boobs were going to pop out if I bent over. I was in a tropical setting and even with humidity, the bra did not feel uncomfortable nor did I feel like it was irritating if I sweated. However, I am updating my review to take some stars away since I have noticed that I now have bruises or marks on my chest after wearing the bra. Many other reviewers noted this as well. I did not notice until a few days after wearing the bra, but I definitely have dark marks across the sides of my chest. I am not sure if these are scars or what. But they are unattractive and I have no idea when they’ll go away. So it loses two stars because while it’s a great bra in function, there is NO reason for it to leave marks like this. And given that many people comment on it, I am not sure why they have not re-engineered this to avoid that.I was really impressed with this bra. I haven't worn (or bought) a strapless bra in a looong time. So long that when I was trying to pack one for a vacation, I realized the cup size for my old bra was maybe 1-2 cups too small, so that means it's been long enough that my body has changed significantly. Items that require a strapless bra aren't my go-to outfit of choice in any case. But I am going to a very warm location, so that meant a lot of things with fine straps. I needed a bra really last minute (ordered this like 2 days before my flight) and I have a larger chest (40 DD). And based on some of the reviews, I was concerned the bra wouldn't fit. But this bra was a PERFECT fit. I was shocked. As a disclaimer, I already wear Vanity Fair as my daily bra (I own the Beauty Back Smoothing Full-Figure Contour bra in 4 colors), so when purchasing this I took a "gamble" and bought my regular size in VF. When I opened the package, I was nervous because the cups looked HUGE. I was like, "no way is this going to fit." But I tried it on and it was great. First off, the silicone grips around the back really make this thing feel like it will not budge. I did not hop up and down or anything, but I did feel like it was kind of suctioned to my skin. And to pull it up or down I really had to grip it. And the cups also fit great. I guess there is something in the construction between a regular "strapped" bra and the strapless in which they might distribute the cup differently. They know what they're doing, in any case. Because I felt it fit great and did not have a ton of gapping and didn't feel like the cups were going to bend over or my boobs fall out. I don't think the back had a ton of stretch, and I was nervous I wasn't going to be able to get it around me, but, again, it was perfect. I wore mine on the furthest out hooks, but to my understanding, that is what you're supposed to do with bras (and then move in to the tighter ones as the bra becomes worn). I also think this is a high quality bra. In waiting for this bra to arrive, I did pop into Walmart to see if I could pick up something in person, and the only strapless bras they had were Maidenform. While it was maybe a few dollars cheaper than this VF bra, I did not buy the Maidenform bra because it felt flimsy and uncomfortable. So I'm glad I held out to wait for the VF bra to come. Very happy with it so far.
