Very functional and spacious!
Color: Upgrade-apricot, Size: 16 Inch
I wasn’t expecting to love this backpack as much as I do, but wow —it’s everything I wanted and more. The apricot color is soft and pretty without being too “girly,” and the fabric has a nice matte texture that feels durable yet lightweight. It doesn’t have a plasticky smell at all, just a clean, new bag scent right out of the packaging. The compartments are super well thought out. I can fit my 16-inch laptop, chargers, skincare pouch, and even a change of clothes without the bag looking bulky. The back padding is surprisingly comfy, especially during long airport days, and the straps don’t dig into my shoulders. It sits well on my carry-on handle, making it the perfect travel companion. If you’re into functionality and aesthetics, this is it.

Comfortable & Sexy!!!
I was looking for a sexy, comfortable bra to wear at home. For those with large breasts, I'm sure you understand the frustration of trying to find a bra that doesn't look you're in a back brace. After ordering this style in two cup sizes in three band sizes each, I found the fit that was best for me and now own three of these gorgeous bras! I could have made do with three or four of the six of the sizes I ordered, but the 38G provided the most comfort & coverage. Speaking of coverage, this isn't really a balconette bra as the breasts are completely covered by fabric. I LOVE that the sides don't cut in and come up high enough to cover any underarm bra fat. Even with the complete coverage, this bra is VERY sexy because of its sheerness. My husband has always complained about my other bras being too thick when he'd come in for an embrace and a squeeze, but he loves this one! It does allow for erect nipples to show through a shirt, so it may not be appropriate for every occasion or for those that are concerned about that sort of thing. For me, this bra is perfect for around the home or for quick errands out. It's very comfortable and sexy enough to wear to bed as lingerie with pretty panties under a sheer robe or just under a nightshirt. It provides medium support as far as lift, but it does allow for quite a bit of bounce which the hubs also enjoys, lol. With this bra being so reasonably priced, I'm hoping it comes out in several more pastel and bright colors, especially red, because I am ready to buy them all!

Favorite bra
Size: 36F, Color: Black
LOVE this bra. The straps sit a little wider on the shoulders since it's a balconette, but it is so comfortable and I have not once felt the need to immediately take it off when I get home from work. I've even gotten into bed forgetting I had it on. I don't agree with reviews stating to size down, and I feel like it fits just perfect as long as you've got fresh measurements and know your current size. Aside from being comfortable and practical, it's pretty sexy since you can see through it. I now own it in blue and black, and I'd love to see some more color options.

New favorite bra!
Size: 42G, Color: Black
I loveeeee this sheer bra. I have a large chest and often struggle to find supportive and lifting bras that don’t add bulk. I loved this so much I ordered 3 more. This actually is great for larger bust sizes. I was shocked.
