TikTok leggings

TikTok leggings are the scrunch bum leggings that went viral on TikTok: high waisted, with a ruched seam down the back that lifts and shapes the bum. Ours are the Evolve Seamless Leggings, squat proof and knitted without side seams, in 18 colours and sizes XS to XXL.

What makes them TikTok leggings

The scrunch bum is the detail everyone films: a gathered seam at the back that gives shape without padding. On the Evolve Seamless Leggings it sits under a tiered, supportive waistband that stays up through squats and lunges, with contouring panels knitted into the fabric. See every pair with the detail in our scrunch bum leggings.

Viral leggings that pass the squat test

The test every viral pair gets is a deep squat in front of the camera, and both styles here are squat proof. The Evolve Seamless Leggings are made from recycled Lycra, with a long, narrow gusset for more stretch and less chafing. For a back without the scrunch seam, the Legacy Sculpt Leggings are a mid rise pair in nylon and spandex, in three colours. See more squat proof leggings and mid rise leggings.

Frequently asked questions

What are the viral TikTok leggings called?

Usually scrunch bum leggings, sometimes ruched leggings: high waisted leggings with a gathered seam at the back that shapes the bum. Ours are the Evolve Seamless Leggings, which are squat proof and come in 18 colours, in sizes XS to XXL.
Are TikTok leggings squat proof?

Ours are. The Evolve Seamless Leggings and the Legacy Sculpt Leggings are both squat proof, with a supportive waistband, so they stay opaque when you squat deep.
Are seamless leggings better for workouts?

Seamless leggings can be a great choice for workouts because they are designed with comfort and performance in mind. The seamless construction means fewer seams, reducing the risk of chafing or irritation during exercise. This makes them ideal for activities that involve a lot of movement, like running, yoga, or weightlifting. Powerlete seamless leggings are made from stretchy woven material that offer a second-skin feel, allowing for a full range of motion without restriction. Additionally, they often provide a flattering, smooth fit that contours to your body.
How tight should gym leggings or shorts fit?

Gym leggings or shorts should fit snugly but not feel overly tight or restrictive. They should hug your body comfortably without digging into your waist or thighs. A good fit means the fabric moves with you without bunching, sagging, or sliding down during your workout. You should be able to move freely, squat, and stretch without feeling restricted. If you notice any discomfort, pinching, or see the waistband rolling down, the fit might be too tight and you should try a size up. Conversely, if they’re slipping down or feel loose, you might need a smaller size. The right fit provides both support and flexibility, allowing you to focus on your workout without distractions.
How do I wash and care for my activewear?

To extend the life of your activewear, wash it in cold water on a gentle cycle and skip fabric softeners. We recommend washing seamless pieces like leggings and shorts in a separate bag away from items with zippers, Velcro, or other elements that could damage the fabric. Always wash them inside out and avoid using a tumble dryer for the best results.
