Customers praised the "buttery soft" fabric and flattering fit of these leggings and shorts. The invisible scrunch enhances the booty while staying comfortable. Reviewers loved the support, stretch, and squat-proof material. Some noted sizing runs slightly small and fabric may show sweat marks. A few mentioned the waistband can roll down and requested pockets.
- These shorts are so comfortable!!! They don't ride up and are so comfy
- Amazing quality. They also feel amazing to touch and make that booty look 10/10
- This fabric is like skin and it doesn't move when you have sized correctly
I absolutely love the fit and feel of the leggings. I was hoping to discuss an issue with them though. I have added a photo of a small hole I noticed when trying them in the first time. This is the third pair I have purchased and have not come across this issue before.
Favourite shorts, makes me feel like a sexy Ned Flanders.
These are the softest pants I’ve ever worked out in. Great quality
The most comfiest leggings I have ever bought! I am 178cm tall and the tall sizing is just perfect!
Absolutely love the fit, the colour and how flattering these leggings are\! 😍 They hug all the right places, are super comfortable, and are perfect for both leg day and everyday wear\. Definitely a new favourite in my gym wardrobe\!
Really great fabric, soft and comfy.
I really like the subtle scrunch effect, which is just perfect. Great color thatI recommend! I wear S for the leggings and am for the top which are my usual sizes.
Lovely shorts. Fit so well
The lift and sculpt that these shorts give is insane! I have three pairs of the aura peachy leggings and just had to try the bike shorts, so glad I did! These are my fave pair to workout in and perfect for the warmer weather workouts!
So comfortable 🫶🏻
These shorts fit like a glove! The fabric is super soft but very supportive. I've been using them for my Cross Fit training and they stay put with no riding up or rolling. I'll definitely be purchasing more in a variety of colours.
Comfy and well fit
My favorite legging: the fabric is so soft and light, true to size, love the design and great quality
Learning that anything Aura is one of my fav materials. Super soft and feel great on.
Great leggings! Love the color!
I love how flattering these are and they don’t ride up
Soft and comfortable and high quality material
I absolutely love these leggings. I now have 2 pairs and Im on the waitlist for 3 more colours in XXS. Can't wait for more colours. Comfy, soft fabric, and without sounding weird, make my small butt look actually look good haha 😆
