Perfect Bra - Sailor Blue


Size Guide

The name is no joke. The perfect bra really is the perfect bra. The flattering U-shape neckline and charming cutout back design allows for both support and breathability. The long length bra can also be worn as a crop top and provides more coverage in the midsection. If you’re looking for the one bra you can always go to, this is going to be the one.

My favorite bra design by far

I love this bra so much, I have it in four colors: this and the plum from the marble collection and the pink and black ones from the sugar plum collection. The neckline is very flattering, and it’s the most comfortable me bra I’ve ever worn. I even wear it underneath my scrubs at work

The best

I already have a lot of Popflex clothes but this one is something extra 😍 It’s soft, comfortable and it fits even a smaller bust girls (you know what I’m talking about 😅) plus the color is sooo cute. Even people in the gym were complimenting on how nice it is and everyone was asking where I’ve bought it. Especially when you wear it as a set with the leggings 💙
To sum up, if you’re thinking about this set - buy it, it’s worth every dollar!

Super Comfortable

This bra is super comfortable and the straps don't dig in when I adjust them, which I like. I might have gotten a size small though because it doesn't feel as snug as I'm used to my sports bras feelings, but it's certainly not loose either. I still love it and am keeping this one and may try the small in a different style next time (:

Love it, one minor complaint

Rounding up to 5 stars but I would give it 4.5–the color is beautiful, the fabric is soft and lush. I have the perfect bra in rose and it fit tighter in a good way, feeling more secure. The back strap rolls up a lot which is annoying and my only complaint. It’s still super comfy and mostly supportive during my workouts. Hope they do continue to make this one in more colors! But maybe just go back to the support the rose one had.

Not Sure It’s “Perfect”

I have a larger bust (36DD) with a small-ish waist so trying to find a sports bra that works for me is hard. I bought the gulch bra (size M) from the terrain collection and loved the way it find around my waist, but not my chest. So this time I decided to try a Large for this “Perfect” bra to see if I could get some more coverage. While I feel like there’s more fabric, there’s not necessarily more coverage and the large is a little to big around my ribs now. I do love the feel of the fabric and will probably keep the bra, but it’s definitely not perfect. On top of that, I feel as though the cut-out in the back actually hurts the support of the bra, the skinny strap that is holding up my chest is not big enough or thick enough to do the job on its own. It also starts to ride up in the back, which drives me nuts. I would probably wear this casually or while doing yoga, but never while running or doing an intense workout. I think I will have to stick to a more traditional Nike style sports bra, just based on my chest and waist size and also it’s compression to hold everything in place.

I haven't bought a Popflex outfit since the Constellation collection, though my wonderful sister gifted me the baby blue outfit from Retro Rainbow! I got the cargo pants AND perfect bra in this absolutely GORGEOUS sailor blue as a reward for myself. I have been eyeing out all the amazing collections that Cassey has been putting out and FINALLY allowed myself to get something, money really is a tough one to let go of especially when you don't have much. BUT THIS.. was WORTH IT ALL. I was worried at first as the Constellation collection I had some trouble with fitting my shorts, leggings and bra as some of it seemed smaller than it actually was. But this fit like a beautiful baby sheep cuddling you, is that weird? Haha. It is soft, buttery, looks incredible and the blue is so beautiful especially on me. What a great pop of color, I can't wait to go out in this esp as summer comes. Take a run at the beach~ I am so happy with this and I do hope to get more things in the future. Thanks Cassey for not giving up and constantly bettering yourself! <3
