Soft material and so flattering! 🩷

This was my first time ordering from Popflex and this runsie was so soft and flattering! The color is as shown and the mesh is surprisingly soft as well so it molded to my body really well. For reference, I’m 5’7” with a 26” waist wearing a Small. I already got so many compliments wearing it! 💞

Thank you for your review! We hope you continue to love your runsie and thank you for choosing Popflex!

I typically wear crop top & shorts to the gym and I’m never going back lol! The runsie Is super comfortable and is so much easier because I don’t have to worry about tops or bottoms pinching me in the tummy area! The mesh on the sides smoothes me out so nicely im obsessed! Also no wedgies like i usually get from these types of styles!! For reference im 5’8 145lbs & wearing a medium 💓

So glad you love it!

It has super powers

I think this is called the supershort because it has super powers! It boost confidence and endurance! I teach High Fitness so I go for a full hour I get super sweaty! The fabric on this not only feels amazing but it stays in place and keeps you dry! I love how much thought went into this the pockets, adjustable straps, built in short with anti camel toe, peek a boo vent. Very functional and beautiful!

Thank you for giving us a 5-star review!

Maybe it's a sizing thing?

I really wanted to like this piece, I was super excited when I purchased it but it was a disappointment. Maybe this is a sizing issue, but due to me purchasing during the warehouse sale, I can't exchange.

First, I think the idea and design is super cute, so 5 stars in that regard. The straps are super thick and comfortable, however if I tighten them to the length I need, they dig into my armpits but if I loosen them, there's gaping in my boob area. I based the romper off my lower half as it is bigger. While the bottom half seemed to fit at first, it's an awkward length and gives me a diaper butt. I'm very confused about sizing. I got the large and my bottom half has gone up to a XL before, however the ruffle shorts gave me a diaper butt as well at a large. (I returned the ruffle shorts due to this). The skort I got as a large was a little big in the waist but fit in other places. I am large according to size chart and measuring correctly.. maybe I am a medium in this super short style?

Again, this may be a sizing issue but the shorts ride up a LOT in between the thighs. I get a wedgie in the back. I have gaping in the boob area, the mesh gets bunched up. The torso length I think is too long, but again if I tighten the straps, it cuts into my armpits. I'm overall uncomfortable and a bit confused.

My fault for ordering during the warehouse sale for something so pricey.

Thank you for your review! We appreciate your feedback and will take it into consideration for future designs. Thank you for your support!

Cute but SHORT

This runsie is very well made. The mesh paneling makes you look pretty hawt and not like a child wearing a onesie. I love the look! However, I probably would reconsider running in this because the shorts are so short and I worry they may ride up. It’d be cool if the shorts length was just a bit longer! For reference, I’m 5’7 and purchased a small.

Adorable! Thank you for sharing!

I got an XL it’s definitely snug in the boob area, but not uncomfortably so. Also, pockets are so deep my entire forearm disappears with my hand open.

We're so glad that you love it! Thank you for your review!
