Size Guide
Find your fit before you check out. Every measurement below is the garment laid flat — match it against a piece you already own, or measure your body and size to the closest range. Bodies are beautifully unique, so treat this as a guide.
Still unsure? Email orders@musclenation.org — our team will help you dial it in.
How to measure
Use a soft tape measure and keep it level. Measure over bare skin or close-fitting clothing for the truest reading.
Quick fit check
Enter your measurements to get a starting size for bottoms.

Inseam & Length
Inseam is the inner-leg seam length. Our Aura Straight Leg Leggings now come in three leg lengths — pick the one that matches your height.
Aura Straight Leg — inside leg by fit length
Short suits ~150–163cm, Regular ~163–175cm and Tall ~175–188cm. Inside leg is measured flat from the crotch seam to the hem.

Aura Peachy — Rise
The Aura Peachy range comes in two rises. The High Rise waistband now sits 4cm higher than the Mid Rise for more coverage and core support.
Choose your rise
Both rises use the same buttery Aura Peachy fabric and sculpting scrunch — the only difference is how high the waistband sits.
Shorts — Inseam & Rise
Inseam length by short style. Use the bottoms chart above for waist & hip sizing.
Sports Bras
Measure around the fullest point of the bust and directly under the bust.

Tees
Measured flat, not worn — match against a tee you already love. Oversized tees run a true super-oversized fit, so we don't recommend sizing up; size down for a less oversized look.

Customers praised these bike shorts as "buttery soft" and "incredibly comfortable." Most found them true to size with perfect length, flattering fit, and squat-proof fabric. The scrunch detail and leopard print received high marks. A few noted sizing runs slightly large or material seemed less stretchy. Overall, highly recommended for workouts.
- Hands down best shorts I have. Super flattering ridiculously comfy and the perfect cut.
- I live in these now. Comfy buttery soft.
- The fit and fabric is just perfect. Firming without being too tight.
Nice fit
The signature scrunch bike short are my absolute favourite and go to shorts! Super light weight, soft, and flattering.
Softest and super comfortable- total perfection.
Love love! Great length and fit perfectly!
Signature scrunch is my hands down fave range !!
My fav tights, perfect length and heart shaped bootay
Hands down best shorts I have. Super flattering ridiculously comfy and the perfect cut. I say this everytime but I mean it everytime I get a new pair I love them even more than I thought 😁
Obsessed with the print and have already ordered a few different styles. Exactly what I wanted and fits perfectly!
Amazing material and really comfortable with the scrunch bum.
Great pair of shorts, I wish there wasn’t a seam running up the front only a minor design flaw in my opinion. My absolute favourite gym shorts by far.
Perfect fit especially around my thick legs. They at my favourite for training as they don't ride up my legs. Shipping was fast. Thank you
Sexy shorts and so comfy love this length
Inlove with these shorts!! wish the rise was slightly higher as I’m 6ft though but they are so flattering and will definitely buy more !
Being a little chunky I’m always super anxious buying shorts online without trying. I was incredibly happy to put these on and have ZERO rolling, still thick enough when bent over not to be see through and a flattering length. 1000% recommend to anyone.
Finally got a pair of black bike shorts. They are so comfortable. Great quality and wash and wear well. Great design overall with the scrunch bum.
Sooooo comfortable, my favourite ❤️
New favourite shorts! Love these to workout in, the scrunch is probs one of the best on the market and the fit is perfect! Doesn’t roll too which I love!
Feels amazing on, little bit shorter then I’ll like but overall they feel great !
Love love love these shirts, can’t flaw them.
Love these! And the little bit of extra length compared to the booty shorts make these acceptable for work attire as a PT.
Estoy encantada con los shorts. El tejido me parece buenísimo, el estampado ideal y me veo genial con ellos. El modelo scrunch es perfecto para realzar glúteos.
This is my second pair of these, what can I say I’m obsessed :sweat_smile:
By far my favorite pattern
Such a staple! Always so flattering and comfortable.
My favorite of all time
