Damn it, if this isn't the best bra I own.
I ordered a small and I am a 32C currently (my bra size fluctuates because my weight fluctuates between 114lbs-130) and at my max weight, it still fits wonderfully.
The bra is snug without causing extra skin or body fat to fall over the top, it looks very well made and the color looks sharp and unfaded (black), it positions perfectly on the body without riding high on the back, I find that the bra is comfortable and supportive (if you have a larger cup, I'm not sure it would be supportive enough for running), and lastly... this bra makes you feel like a damn goddess, it looks so awesome!
The shipping took a while, but that was made very clear at checkout and it was definitely worth waiting for.

I want to start by pointing out the biggest thing here. This bra is ATTRACTIVE AS HELL and is COMFORTABLE as HELL. Some other things could use work, but I think for my version of a "bralette that is almost a sport-bra...." this will be it.
It's BEAUTIFUL to start off. The design is fabulous and the areas not on the breast as truly well made, thick and just gorgeous. Perfect for "off the shoulder" or sheer styles because you'd have NO shame showing this off as carefully made and flattering as it is. HOWEVER. I have large C cups and wear a 34 and this has virtually NO hold and has NO padding at all. It IS essentially an upgraded "bralette". Meant to cover nips and maybe smooth breasts, but has zero support and no ability to "lift" or "pad" breasts even like a sport bra.
But I still love it. It's SOOOOO freaking comfortable AND pretty. Whatever peeks out looks like valid tops/lingerie/bralettes. But it FEELS like butter or nothing at all. And I'm someone who avoids ALL bras unless I"m going to a special event or something. This feels like YOUR skin. Will you get voluptuous life and bumps? Nope. But you'll get gentle support and attractive design with MAXIMUM comfort and NO Uniboob. It's like a Bralette for actual Adults. I bought a bunch of "80's inspired" raw, off the shoulder tees for around the house and some off-the-shoulder sweatshirts for the same reason (and to mix with Winter styles) and this is truly the FIRST bra that has advertised as "comfort" but also "sexy bralette" and has actually delivered BOTH.I own like over 100 bras. Easy. And this is better than a sports bra, sexier than a Victoria's Lounge bra, more comfy than "soft bras", but still looks "young and hot" like the bralettes that 25 year olds wear. This can make a 30+ woman look sexy. I'm going to buy every color of these. They feel like actually being naked and I'm a woman who refuses bras 99% of the time. I forget I'm wearing it. And that says something.
