Review: Budget friendly, great quality!! - Love these! Very comfortable, look nice and fit well. I purchased one and liked it enough to purchase several more. They are sturdy and flattering with great coverage and support. They hold their shape after washing.
Review: BUY. THIS. BRA. - Okay, so I have a LOT to say about this bra. I'm sure you're reading the 1 and 2 star reviews and wondering whether you should take a chance. YES, by all means, do! I am going to do my best to address the issues raised in the low ratings. But first, please know that I have been wearing the bra for two days now (all day) and can tell you without reservation that it is one of the most - if not THE most - comfortable and attractive bras I've ever owned. I am rather chesty (a 38D) and usually have to try many bras on before I find an acceptable one, and then I buy like 3 or 4 at a time. I've worn Bali (though, not a ton of styles), Warner, Soma and others that perhaps I've long forgotten. TAKE A LOOK AT MY PHOTOS and keep in mind that I am approaching my 64th birthday. So, needless to say, the girls are not naturally perky at this stage in my life. LOL. I included one clothed so that you can see how it looks underneath a summer top. So, as to the issue of fit: It fits VERY true to size. The cup size fits exactly like a D-cup should fit - no gaps, full coverage, no side spillage out of the cups. Underwire: Truly, I have no idea what the complaints are all about. There is more than adequate fabric covering the underwire, and it is very comfortable too. If people are experiencing bruising (really???) or marks, perhaps they have it on hooks that are tighter than required, or maybe they need to go up to the next numeric size (e.g., 36 to 38). As I said, I've been wearing this bra all day long for two days, and it doesn't even feel like I have it on - it's THAT comfortable. Straps: They adjust well and give a good range for just about any body. I found that the girls are not sagging and are well supported. Sure, it would be easier to have them adjust in the front instead of the back, but once you make your adjustment, it's not like you have to do it every day (unless you're switching back and forth between racer-back and standard). BTW, I am wearing it as a racer back today, and it's fabulous! Padding: Unless you have literal bullets for nipples, there is no way they're gonna poke through the padding. The cups are not overly padded, which is really nice IMO, because too many bras have quite heavy padding, which is hot and uncomfortable and makes your chest look fake. Embellishment: The mesh portion on the upper cups is really attractive and lies perfectly. I haven't found issues with gapping, unevenness or seams showing through the clothing. I suppose if you wore a really tight top that is maybe silk or satin, you might see something. But for everyday use, the seam is it is not an issue. Bottom line: I am ordering two more bras today in different colors. If there is any deviation from this review regarding quality, etc., I will update this review. HOPE THIS HELPS! UPDATE (11/14/24): Still 5 STARS! I've been losing weight (down about 35 lbs. since June), so I've ordered several more of these bras in 36DD & 34DD along the weight-loss journey. They remain my "go-to" bra. Even after repeated wearing and washing, they are super durable and have retained their shape and fit. I'm about to go to a 34D and will definitely be ordering again - will use the larger ones for working out at the gym ;-).

### ⭐⭐⭐⭐ A Nearly Perfect Bra
*by E***Y on May 8, 2025*

I liked this bra enough to order 2 more, because I found it to be very comfortable and thought it seemed like it was good quality. I struggle to find bras that fit perfectly, and this one is the first one I’ve found in a while that offers the coverage I wanted, without the side spillage. The support is there, which to me means that band is the correct size for me, as I’ve noticed the adjusters on the straps tend to move as the day goes on, but I don’t notice any sagging. I think they give me a nice shape, and I feel confident in my clothes. This bra is a bit noisy, unfortunately. I notice a creaking sound throughout the day when wearing it. It might not be as loud as I perceive it to be, because no one around me ever asks what that sound is, but I wanted to share that it definitely makes noise. Otherwise, I think this is a solid choice for a decent bra at an affordable price.
