Not that flattering and fits really tight

According to exact measurements on the size guide, I'm a size XS, but I usually want my tights to fit more comfortably (not pressing down on my stomach) so I was going for a size S, but reviews said it's a smaller fit so I went for a size M.

It was still too small lol soo tight. Especially around the thighs (I would say my thighs are average, and if yours are built then it'd definitely be a squeeze) and even around the waist where I allowed for 2 sizes up compared to my actual measurement.

As for the invisible scrunch, I had high hopes but it's not great :') maybe if I had more glutes lol but I barely noticed a difference. Maybe because I went 2 sizes up? But it was still wayy too tight on my waist so I wouldn't have been able to size down anyway.

In short, I will be returning but hope this helps people with sizing :) If you like a bit of room on your tights (don't want a super compressive fit) then get a few sizes up, but the scrunch effect will be reduced.

Great tights!

Thick, squat proof and super comfy! Only downside, I’m 173cm and they’re def 7/8 length on me ☹️ wish they were made longer…..and in more colours 🙌🏻 but overall, excellent tights!

I wasn’t entirely sure how these would fit, but they are so so comfortable and squat proof! They also sweat really well and don’t show up as much as other brands.
Only issue is I wish they would bring out more colours! maybe dark navy or a forest green colour!


Fiancé loves her tights. “Best leggings ever”.
Brought as a gift and arrived fast. Certain she will buy again from Active Basics.

Not for me

I’m 164cm tall and bought a L as per size guide, also my usual size. I feel these leggings sit at 7/8 length, not full length. They also roll down when working out. The leggings sit below my bellybutton so I wouldn’t say they are high waisted.
The scrunch does sit nicely and looks good. Material feels nice.
