The most flattering and comfortable thing I’ve ever put on my body

Hey guys!

Today, you are witnessing the beginning of something new.

In 2016, I started POPFLEX to make cute workout clothes. Then as the brand evolved, and I evolved, the mission became so much more. It became about solving problems. It became about innovation. It became about making the best fitting clothes in the world for women.

8 years I’ve practiced making activewear. And today, I challenge myself to expand into a new space.

Today I introduce you to Popflex Active Casual.

I’m taking all the comfort and performance features from my workout wear and integrating it into casual wear, because WHY NOT? You guys have lives outside of the gym and I wanna be there with you too.

I’m starting with my favorite closet staple: a jumpsuit!

The Go With The Flow Jumpsuit


The Go with the Flow Jumpsuit is literally the most flattering and most comfortable thing I’ve EVER put on my body.

The cut

This is a wide-leg jumpsuit which means the lower half is super flowy and the top is more snatched. It has a wide, square-cut neckline and a racerback. You can dress it up or down and wear it literally anywhere.

You have OPTIONS

I love it so much that I had to make it in multiple inseams (petite, regular, tall) AND in a sleeveless and long sleeve version…WITH THUMBHOLES.

This comes in XXS to 3X and is extremely stretchyyy! You can get your normal size if you like things loose or you can size down one if you want a little more waist snatch. I also made the inseams extra long so that you can wear it with heels, which is how I like to wear my jumpsuits! I’m wearing the XS in the regular inseam with heels. I’m 5’5”.



What do you think?!

Are you making the Go With The Flow Jumpsuit your fall staple outfit?!

This is the beginning of Active Casual but it doesn’t mean it’s the end of Activewear. I’ll still be designing your leggings, sports bras, and hoodies, but I hope from here on out I can make clothes for you in more parts of your life.

    Could you make a jumpsuit with short sleeves? For the people who don’t want long sleeves but don’t look good in tank tops.
