My FAVORITE Bra!
Size: 44F, Color: Black
These are my FAVORITE bras!! They hold everything in and there is no spillage out of the cups! I own many of these and have yet to be disappointed. I like that they don't cost and arm and a leg either!

Decent low-profile bra, but with caveats for larger chests
First, I had to return the bra three times because the size charts on the manufacturer's website are laughably wrong. By measurement, it had me at a DD. Lo and behold, I was an H. So ignore those size charts, and go off the standard US ones for bras. The band sizes are also near the US standard, but about one standard deviation too small. I'm normally a 36, but I had to buy a 38 in this. The website had me at a 34DD, which was absurd. You should have seen the look on my face when it came and I knew instantly it wouldn't fit. The 38H did, though. I'm typically a 36-38 or H/I/J in most brands. So the pros. This is a great bra if you want to get rid of lines. I have a lot of professional silk blouses, and I can't wear ANY lace underneath them or you can see it. This comes in a lot of neutral colors, too, which is great for those purposes. The shoulder straps are really chunky, which makes it hard to hide in tanks, but it's very comfortable in all other styles of tops. The back strap is quite firm for a bra in this price range, so that the majority of the support is from there, not the shoulder straps. The bra (once I got the right size) actually tacks in the middle, which is rare for me unless I spend over $50 on a bra. I'm also not getting unattractive areas of fat accumulation that happens when your bra doesn't fit and pushes breast tissue out of where it should be. This was important to me, because I want to eliminate lines, and nothing points out where your bra straps are like a small fat roll right under your bra band. The cons don't outweigh the pros, but you should be aware of them. First, the cups are very full-coverage. Anything past a moderate scoop neck will show the bra. I prefer a little less coverage so I can wear mandarin collars. Second, the cups don't have any support outside of the band, shoulder straps, and underwire. If you want your chest to sit high and tight, you're going to have to spend more. It certainly uplifts more than going without a bra, but for larger chests, you're still going to droop a bit more than a bra with firmer cups. This isn't a problem for me with looser and more professional blouses, but I don't like how it makes me look a bit "sloppier" in tighter shirts. For a bra that was $50+ dollars, the cons would make me not purchase it again. But I paid $26 for this, so the cons are quite reasonable for price point, given that I do have a large chest that makes bra shopping quite the chore. It fits the bill for the task of the type of shirts I needed it for. But if you're a full-chested person and want a bra that will work for nearly everything, you're going to need to look elsewhere and spend more.

Finally a bra that fits!
Size: 38G, Color: Black
This is my first time wearing this bra, and right away I can tell it’s the best fit I’ve ever had. I wear a 38G, and the support is incredible without feeling tight or uncomfortable. The band sits snug (on the first set of hooks—yes!) and doesn’t dig into my skin. The cups give full coverage without spillage, and the lift is exactly what I needed. So far, I’m very happy with how it feels under clothes, and I actually feel supported and comfortable. I will update this review after two weeks of wear to let you know how it holds up.

Not durable
I love the initial fit and feel of this bra. Its very comfortable and silky. I was disappointed to discover the poor design which allows the underwire to poke through much too quickly. It happened on both of my bras from this company. I bought 2 hoping the first was just defective but the second had the same issue in the same area.

Great coverage for a chesty gal with smaller band size
Size: 34F, Color: Gentle Rose
I don’t know why I can find bras that fit better on Amazon than in store, but this one is a good one. It fits well and is as comfy as you can expect from an underwire. It has zero lining and that can be an issue, so pay attention to that if it is important to you for the nip coverage!
