🔧 Pro Tip

The 72-tooth ratchet is a game-changer when working in confined engine bays or tight under-dash areas. Utilize the deep sockets with a small extension for reaching bolts on suspension components or spark plugs, while the standard sockets are perfect for everyday fastening tasks. Always ensure your blow mold case is properly latched to keep your extensive collection organized and secure.

Cute but could be better
Color: Dark Pink, Size: 38DD
This bra definitely looks really good and has a sexy style to it. It does a decent job overall, especially for the price, but after trying two different bras from the same brand, I honestly liked the more expensive one much better. The lace on this one is pretty, but it shows through thin shirts and tighter materials. The underwire also started digging into my skin after wearing it for a bit, and the lace caused some irritation. The fit wasn’t bad, but the pricier version was noticeably more comfortable and fit better overall. For $16, this bra is still decent and looks nice, but if you’re deciding between the two, I’d recommend spending a little extra money on the more expensive one for the added comfort and better fit.

Best bra ever 💯
Color: Dark Pink, Size: 38DDD
I have seen these bras hyped everywhere especially tiktok, so I was expecting to be somewhat disappointed. Instead i am shocked by how much I love it and am immediately looking to buy more of them!! This is the most comfortable bra I have ever worn. I am a 38DDD, and it actually does appear to minimize and lift my chest in shirts while being so much more comfortable than any other bra. My back pain is gone???? Its affordable??? 100000000/10. Buy it 😭😭

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.
