How to measure👇
I am a size 12 in dresses and a 36A in bras, and this romper will not stay up. The top slips down constantly with any arm movement, and the shelf bra then bunches up underneath the boobs. There are loose threads on the shorts, and the clasp to make the straps into a racer back is a bit uncomfortably too high up on your back. I also wish the fabric was a natural fiber for a better feel. Overall, the piece is cute, but I expected more.
I’ve been on the search for cute and breathable athleisure to wear at Disney world and I think I found a winner. I wore it during cma fest over the weekend and got so many compliments. Everything felt supportive enough and never overheated. Highly recommend. Also a winner for tall girls!!
I love Popflex's products and own many pieces from the brand at this point but what I have come to finally accept is that I shouldn't purchase anymore onesie styles from them because they never work for me. The Cinch Up Shortie is super cute but the fit is just not it for a girl with longer torso and bigger chest. I sized up hoping that it will give me a longer length and more boobs coverage but what end up happening was a lot of fabric bunching up in my back. The good thing about the medium size as oppose to a small size is that it at least cover my chest, otherwise, they would've been exposed. There's absolutely no support in the chest area. Due to the back being so baggy, this became the least cute piece of Popflex I own. At least the other onesies look cute despite not fitting well. I got this during their Black Friday sale so I can't even exchange for a different size or style. My fault, I should've tried it on right after purchasing before storing it away until the warmer months hit. Their Cinch Up Flare Jumpsuit at least fit better in the back than this Shortie version...although the chest coverage is still iffy.
The details, the stitching, the lace up back, it’s BEAUTIFUL. I made a tiny edit where I made a single stitch to make the top more heart shaped and it’s my favorite fit rn. When I first put it on, it kind of reminded me of a wrestling/power lifting singlet from the front, but the BACK omg is perfect. The stitch made the top conform to the bust so it doesn’t “pop” and spill all the goods. I love that I can hook/unhook for a racer back look. It’s similar to what they did for the target blogilates dress. I love the top part of it and wish there’s a dress version with this corset lace up back. Like this with the pirouette bottom would be so fun!
Thank you so much for your thoughtful review!
Fits great, looks great!
I love how soft the fabric is! I’m able to pull it up and down without undoing the laces, which is a huge plus. I could size down to a medium, but I kind of like the extra room in the large (normally between 10/12)
I liked it so much I bought 2 different colors. I would by a 3rd but it's sold out i n my size. For reference, I'm 5'4", 36-27-36, regular length torso and the XS fits me the best. I purchased the navy in a small because thats all they had and it fits good, but then purchased the brown in XS and it's much better. Definitely size down one if you want it to be super fitted but still comfortable.
Fit was perfect and this outfit is so flattering. I was worried my hip dips were going to look huge, but this material is forgiving
So cute and comfy!
Cinch Up Shortsie - Pecan
It’s cute. I don’t love it as my body is post baby and needs some assistance lol.
I like it. Honestly probably wouldn’t reorder. Wish you offered more tank options
I absolutely love this item, 9/10!!! The only thing I didn't like about it was the shelf bra inside. I have a very small bust, and even when I adjusted the straps, it kept trying to slide up and almost turn the very top hemline inside out in a really odd way. I had to keep adjusting it. Once I start sweating, it stays the way I'd fixed it, but when I'm not sweating and I'm just wandering around, it keeps trying to show the shelf bra above the hemline and distorts the nice, pretty square shape of the neckline. I wish the shelf bra had the bottom of it sewn into the jumpsuit to secure it into place, otherwise, I love literally every single thing else about this. I got alot of compliments at the gym for it, especially the back! So cute and snatchy!!! The fabric stretches beautifully, and it's so extremely buttery soft. The shorts can ride up a little bit during stretching and squatting, but it's really easy to adjust back into place even when I'm super sweaty, it's just a minor inconvenience. That shelf bra though drives me a little bit batty. Am I literally the only one who likes the removable bra pads? I love my old Popflex bras where there's an opening and/or an optional pad pocket with a nip cushion layer so that I can put my bra pads inside. What's the big deal about them moving around in the wash?! Just take em out, not that big of a deal! When your bust is as small as mine, ya need all the help you can get! #teambrapads
I REALLY wish this came in a long like the jumpsuit does, if this had a longer inseam I would've been IN LOVE. But I guess us long torsos can't have it all... The fit was great everywhere else, I tried sizing up but once you cross that line into "plus" sizing the fit, shorts length, etc. is just completely different.
Was a birthday gift for my daughter..she loved it and said it was super cute
This is very cute BUT there is a slight issue. It either rides up my butt and requires fashion glue or constant readjustment. Also when putting my arms forward (ie a plank position) or raise them up, there is a slight chance I might flash them. This can be remedied by wearing a sports bra underneath, its just disappointing bc its cute.
Cute and sexy. The little rings on the straps that let you convert it are brilliant. I got black and plum colors, may get brown.
Love this. Curvy little romper. Cue and can be absolutely sexy.
So SO cute and sexy. I feel like a goddess in this onesie. I want it in every color except brown bc I dont like brown LOL.
Sexy and cute. Great for casual and loungewear.
I ordered the brown color and I think I want a black one. this is sooo cute and flattering! I’ll pair with a sports bra for workouts (D cup) but for at home this coverage is great and comfy.
I love this company!! The clothes are comfy and fit perfectly! They are flattering and don’t slip down or ride up. So so so so worth the cost. Its wuality, its sustainable, its a responsible company and they have a customer for life from me!
Cute, sexy, and flattering. I was a little worried it would make me feel like a sausage lol, but I really love how this looks on me. The color is also really, really great!
Love this shortsie so much. I’ve contemplated buying it for so long and finally did it, wish I got it much sooner bc it’s such a cute every day weekend fit and gym fit. My torso is on the shorter side so I thought it might be unflattering but it’s so cute and feminine! I got the small and I think it’s true to size, though it is very form fitting and I’m sure you could size up without it being too big. This is perfect for the summer and always always love the pockets!!!
This dress accentuates my curves and I love it! The neck line flatters me so much and the overall fit is amazing! Its body hugging gives a really good shape. But sometimes the shorts roll up - somehow it is annoying given the length is very short and I find myself adjusting it more frequently.
