Outfit Ideas + Exclusive Styling Tips!

Our Heather Sky Blue leggings and bike shorts look great with cropped or oversized t-shirts and sports bras or tanks in white and light grey. We also love this style with a navy sweater and to pull together this head to toe laid back version of chic, opt for a pair of the perfect sunnies.

We love our Heather Grey leggings and  bike shorts with black, white, or neon sports bras and t-shirts.  When you're not about the gym an oversized or cropped-and-boxy sweater in black, cream or soft pink can look pretty chic.

This color is GORGEOUS!! You simply have to see it in real life, pics don’t do it justice

After loving my black leggings from Meira Active since March 2021 (and wearing/washing at least weekly and seeing them hold up well) I treated myself to this beautiful Heather blue color and I have NO regrets! They have that great Meira Active fit, where they hug you w/ light compression but do not restrict your movements. This was my first built-in-thong (as black had regular panty) and similarly I do not feel or notice the underwear- everything moves with you. These do not require pulling up or un-bunching through cardio dance/barre/pilates exercises that involves jumping, stretching, standing, floor work, etc. I get sweaty and my heart rate up, but wearing these I can focus on my form and movement, not needing to worry about my clothes. Even though they’re long leggings, they don’t seem to add heat and feel cool enough to wear for a 60-min workout. Seriously the pictures do not reflect this gorgeous palette of blue- just order them to see in real life! A beautiful change from the standard black leggings.

best leggings ever

i love these for school. I can just wear a oversized t shirt and it would look not only trendy but comfortable for the long days and that is what I look for in products and it is great for everyone to try on. I love the underwear that is built in and that is what makes the leggings whole.

First and foremost, the color of these Heather Sky leggings are exquisite. I get compliments all the time on this color, and people are constantly asking where I got these from!!

When I first unboxed these leggings, I got so excited due to the beautiful pale blue color these come in. I have never seen such a gorgeous color before for leggings!

Secondly, I LOVE the fit of these. They do an amazing job at really tightening everything, and making me look super flattering while I am working out.

Thirdly, the built in thong is BARELY noticeable. I genuinely can't even tell, and I normally HATE wearing thongs.

I am honestly so impressed with this company. I keep telling everyone about them because of how amazing they are! Not to mention, it's a woman run company, and I love supporting small businesses.

Keep it smooth

We don't use side seams or a vertical back seam in our undies. We bring you our ingenious thong and comfy classic fit underwear built right into styles made to fit you and your life. We will never try to sell you a typical pair of tights.
