The premium inserts also help provide refined comfort and a tailored fit. The ReboundReduce™ stability bar easily attaches to the car seat when installed rear-facing, helping to minimize movement in the event of a crash.

Good fit, but wire isn’t good for super lg breast
Color: Purple, Size: 36I
While I love the fit of these bras I’ve order almost one in every color, I have to say the wire does break a little easily they always snap right under my under arm now ik I have very large breast I’m between a I and J cup. These are a little tight but you can still adjust them I still love them despite the wire snapping. I’d say they last longer for small breast like my sister I accidentally ordered the wrong cup size and it fit her now she’s hooked on this brand and has an equal amount of colors😂 it’s easy to wash and I wouldn’t say it’s soft because it’s mesh I don’t think mesh is that soft like silk or anything but it’s definitely smooth and see through so my bf and I love that part whenever I wanna get spicy and send a pic during the day.

Weird smell but cute
Color: Coffee Brown, Size: 36H
Edit: ordered a size up from the size chart cup and it's perfect. Wore it all day at work today and it was super comfortable and nothing fell out. I did return this same day but it was too small in the cup. I did follow the size chart but I was still spilling out of the top. But the material was very good quality and the color was an excellent match to the listing. I will be ordering the next cup size up to see if I can get it. Only down side was a TERRIBLE chemical smell when I opened the package and took it out. But it was gone in a few minutes.

The perfect bra!
Size: 46DD, Color: Beige
This is the perfect bra! It’s comfortable, supportive, and the straps do not slide off your shoulders. The material is so soft yet lifts and shapes the sides just like they say it does while also smoothing the under arm and back area. This bra stays put all day and feels like you’re wearing nothing. It’s very well-made with the perfect stretch that covers even under a thin T-shirt. I hate to say how much money and time I’ve wasted on ill fitting overhyped bras but this one is perfection. I will definitely be buying more! My only suggestion is the band size runs a little large so I went down one band size. Cup size is right on.

So comfortable!!
Size: 38G, Color: White
This is the most comfortable underwire bra I’ve ever worn. I am a 38G cup and it lifts, shapes and supports me all day, minimizes, the back stays in place and is super smoothing. It keeps its shape through a few wears. It has great stretch. It’s so soft. Nice bright white. Perfect for an every day / work bra. And it’s super inexpensive. I’ve bought $80 bras that were horrible in comparison. The only one con it has is that because it’s so soft and stretchy, you can’t wear it more than 3 times without needing to wash it. Otherwise it stops supporting as well because it’s stretched out a bit. But I mean, we should probably be washing our bras more than we do anyway, am I right?! 😆

THE BEST. Seriously.
Size: 36E, Color: White
The world is upside down. How can a twenty dollar bra outperform my hundred dollar bras??? I don't know but here we are. I am 49, a 34F/36e, 5'1". Finding a great bra is challenging to say the least. This bra is it, y'all. I bought it in a different color a couple of weeks ago. I wore it three times in a row to make sure it wouldn't bag out, lose its support. I washed it, not in a lingerie bag, on warm, dried it on high, to make sure it would hold up to that. It passed both tests with flying colors. It is so comfortable. It feels wireless! It is very flattering, has great under-arm-flub-smoothing and support. The back is substantial and smoothing but without being bulky or restrictive. The straps are wide, but not too wide, and totally stay put all day. I bought the other three colors and the sizing is seamless across colors. This is a winner, folks!!!
