Super cute and comfortable

I'm 147 cm and 33 kg, XXS/XS isn't skin tight (the shorts are a bit big), but it works. It's incredibly effortless and comfortable, and I don't even notice if I'm not wearing underwear! The cleavage and built in bra is very flattering, and I love how the crotch is designed. I did however experience a nip slip once when I was lying down sideways - my breastfed baby doesn't mind, haha! I also wish it had pockets.

This piece is so cute which is why I’m sad it

This piece is so cute which is why I’m sad it couldn’t take one wash. I pulled it out of the washer and a bunch of thread had pulled and bunched on the back.

i feel so snatched!!

i'm in love!! the fabric is so comfy. i got size smaller to get moreof that snatched look. definitely too small for my C cup, but it won't bother me soon (top surgery). i wish stripes were adjustable, i have a feeling that they might fall off, but otherwise i love the feeling of it!!

I feel fulfilled

Ever since I saw Popflex content on social media I longed for stylish workout attire. I made my very first purchase and people warned me about high tariffs (to germany) but I guess I‘m good? Found my order after (sadly) my workout in the mail box. Tried it on and now I refuse to take it off!!! I’m a couchpotato and feel like doing more sports now which is crazy

Thank you for giving us a try! It means a lot to hear your first order was such a great experience. Hope it keeps you feeling motivated and comfortable.

Looks cute but not finctional

I really wanted to love this piece but unfortunately the short ride up really bad when I use it during Pilates. It is super flattering and looks good when I wear it I just wish the shorts were more secure and wish it had pockets.

Almost perfect!

I also bought this in the French roast brown and surprisingly (to me) prefer the color to my go-to black, but I know this is going to be a staple in my workout wardrobe as well!

The fabric is thick (no nips, no underwear lines) but super soft and sleek to the touch. My only critique is that the straps are always on the verge of sliding down on me, which may just be because I have a shorter torso.

Almost perfect!

I’d honestly give it a 4.5, but rounding down just because it’s almostttt there, but the straps are just a smidge not quite there. The straps just feel…at risk of sliding down. I have a short torso, so I think proportionally that is probably it, but for future designs (please??) it would be nice to have a cross back or halter style or adjustable straps.

Other than that, I have nothing but positives! The color is gorgeous and it’s surprisingly thick! No nips or underwear outlines! The fabric is super soft and very flattering on the butt!

Note: there was an unfinished string on my piece from the bra lining seam on the inside, but it was a quick snip fix!

For size reference: I’m usually an XS in Popflex bottoms and a S in tops, and the XXS/XS fit great with surprisingly plenty of stretch room if I decide to go out to eat after my Pilates class haha

It’s gorgeous!!

I think I would give it more of a 4.5/5 but I still love it!! The fit is flattering, I love the color, and very comfortable. My only issue with it is that the torso might be slightly too long for me so if I am moving a lot the straps start to slide down. But I wouldn’t want to size down because the bottom part fits perfectly.

Thank you for taking the time to leave a review. We are so happy to hear that you love the fit and color. We appreciate your feedback about the torso length and will definitely keep it in mind for future improvements.

Speactacular

This product was everything I could have hoped for and more. I was scared about how it would look because its tight and short. My biggest pet peeve is when shorts pinch at the bottom seem making your thighs bulge out and this didn’t do that. It is so so so flattering I also had to order the xsmall because it was out of stock in small. I’m a size 2, 32C and it fit great! Only only thing is my boobs pop out a tiny bit but nothing a little adjustment every now and then doesnt fix. Cassey delivers on every single claim she makes on her products, on materials, fit and quality. Love it love it love it. Now just waiting for this product in navy blue :)

Teenager approved 🙌

I got this to treat myself and I love it so much! It feels good, nice quality fabric, and it doesn't slide down or anything like that. I'm still kinda self conscious about how I present myself, my body is nice but showing my back and shoulders or chest makes me nervous.

So cute & flattering, nip slips happen

This is sooo cute and flattering, I love the shape and material. However I have a lot of nip slips with it. Idk if it's due to my personal anatomy or a flaw but make sure to move around before you wear it out and about :)

This changed my mind about workout one pieces

Honestly, I bought this so I could get free shipping. BUT I actually really loved this. It's really comfortable, makes me look so snatched. I used to dislike the look for one pieces like these and never understood why people liked them but I get it now. I feel so confident wearing this. For reference, I'm usually an S but I decided to try the Extra Smallflex for a sculpted fit and it was the best choice.

I will say though, I'm docking a star because it's pretty lowcut for me and I feel like it's SUPER easy for my nips to slip out and I'm in no way a busty girl. If I want to work out in these, I feel like I'd be super self conscious of my girlies to pop out. Also, the shoulders kind of slip off sometimes, which doesn't help with my fear of a nipslip.

Glad it changed your mind and you feel confident in it! Thanks for sharing the fit notes and feedback too.

Obsessed with this neckline

It’s surprisingly really cute the neckline detail with the cleavage really sets it off the best feature about it. Im a 34B I got xs holds my girls in nicely. It feels secure, but still sexy,. It was on sale so it was good. I don’t know if it’s worth the original price though but it’s cute.

Thank you for sharing! We are so glad you love it!

SO! Confortable!

This is so easy to put on, so soft, so comfortable! The only thing that wasn’t perfect in my opinion, is that it becomes SO heavy when wet! And for people that sweat buckets like me, it’s feels a little weird (but not too bad!)

Love the fit, but it pilled horribly on the 1st wear

Like the title says, the fit is SO cute, I wore it for a day at Disneyland and had never been so comfy. However, I was so disappointed when I notice how bad it had pulled, for the price had hope that would not happen.

+ to confidence

I feel myself very beautiful in this shortsie, but I am also constantly afraid that my breasts might pop out, although this has not happened yet. If I eat well, tummy looks cute in this shortsie. The stitching from the panties is slightly visible.

I have Midflex.

Flattering and comfy!

Size guide said I'm a midflex but there was a lot of fabric bunched up by my stomach so I ordered a small flex (not pictured) and it was too tight for my preference.
The midflex is really flattering, I LOVE the neckline and back. I've never worn a workout romper so I'm still debating whether it's a keeper. Material is wonderful, so comfortable without being compressive and soft.
