Doesn't slip down
Size: XX-Large, Color: Black
Holds up very well for day to day work and doesn't slip down. Came with straps as well. Material feels great. I would base sizing off of your usual band size more than cup. Got a XXL when measured I'm usually a 38B or 36C and those sizes are too small to be comfortable and it said I'd match with a large so I went up based upon my bra experiences. Pink color isn't really a good pink tone more closer to nude and dull if anything. But all the other styles and colors are great. It feels very supportive and covers all the right places while smoothing out back rolls. It's a good stretch when you put it on to and then conforms to the chest. Pads are a little over the place but they're removable so that's expected.

An excellent strapless option
Size: XX-Large, Color: Nude
Extremely comfortable! It didn’t slip down like some do, so I don’t feel the need to tug it up. Felt like I wasn’t wearing anything at all. I also like that it comes with optional straps. Great coverage. The two things to watch for is the top seam is a little thick, so it won’t work under thin tops, and the pads will move around, but they are easy to adjust or remove. On the whole I find this a great fit and easy to wear, at an excellent price point.

Great!
Size: XX-Large, Color: Nude
REVIEW FROM A REAL PERSON WITH NO FINANCIAL INCENTIVES This is my first time ever wearing a strapless bra and I really like this one! It's very comfy and feels like wearing any other sports bra just, well, without the straps (though they do include straps in the box that you could attach if you wanted). I'm somewhere around a 40DDD and got a 2x and it fits well, though I did wear it to work one day and by the end of the day, it did feel like it was digging/squeezing into my side a bit too much (however it had been 10hrs by then). The bra IS stretchy but if I were really any bigger, I think I'd want to go to a 3x. Only very minor issues with it slipping, nothing even close to where I was worried anything was going to pop out or anything, even after being out in 90F heat.

Stays in place
Size: Medium, Color: White
I’d give the Letts Jolli Push-Up Strapless Bra a solid 3 stars. The fabric quality is actually really nice—it feels soft, smooth, and comfortable against the skin, which is a big plus for something strapless. It also does a great job staying in place. I didn’t have to constantly adjust or worry about it slipping down throughout the day, which is usually my biggest concern with strapless bras. That said, the “push-up” aspect was a bit disappointing. It didn’t really provide much lift or enhancement like I expected, so if you’re looking for noticeable cleavage, this might fall short. Overall, it’s comfortable and reliable for staying put, but it doesn’t quite deliver on the push-up promise.

It holds the girls up!
Size: Large, Color: Nude
This is absolutely the best strapless bra I have ever owned! It stays put, doesn’t ride up or ride down & I don’t have to adjust it. It fits true to size. Worth the money! It’s also not the sexiest bra, but when you just want a strapless bra that holds the girls up, I promise it will do that!
