Size Guide
Find your fit before you check out. Bottoms, bras and tops are body measurements, so measure yourself and match the closest range. Tees are measured laid flat, so compare them with a tee you already own. Bodies are beautifully unique, so treat this as a guide.
Still unsure? Email orders@musclenation.org and 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

Aura Peachy Rise
The Aura Peachy range comes in two rises. The High Rise waistband sits 4cm (1.5") higher than the Mid Rise for more coverage and core support.

Both rises use the same buttery Aura Peachy fabric and sculpting scrunch. The only difference is how high the waistband sits.

Customers praised these bike shorts for their "buttery soft" fabric, flattering fit, and beautiful rocky road color. The invisible scrunch feature enhances shape without obvious lines. Shoppers loved the tummy support, squat-proof material, and comfortable length. Some noted sizing runs small, with one mentioning they rode lower in back. A few felt the thick fabric gathered slightly at front.
- The invisible scrunch gives the bum a great shape without that obvious, prominent scrunch line.
- Great fit. The material is firm and shapes the body nicely.
- Probably the only bike shorts I've ever bought that don't cut into my legs.
Great fit. The material is firm and shapes the body nicely.
I’ve got the same size as the invisible scrunch leggings and it feels like it runs a bit smaller, but no problem. Colour is beautiful! It’s says that the colour may fade or transfer but I had no problem with that after a couple of washes. Fabric is soft and feels good on touch
5 stars
Love the colour and fit
Great fit, thicker material than I expected
Love the length of these shorts. Gave a snatched thigh effect.
Pretty much perfection for me. So flattering and secure, doesnt roll up or down. A pocket wod make them perfect and wish they wer in many more colors
5 stars

Love the material and the length. Unfortunately I have a bigger butt so the do rode slightly lower in the back than I prefer but still a great pair of shorts
I can safely say my butt looks amazing in these. I don’t know how it works but it does.
great colour, perfect fit and feel lovely
Absolutely love these shorts! The colour of these are just stunning! 😍
The fit and length are perfect, and they stay put without rolling down at the waist. I don’t have to constantly pull them up or adjust them, which means I can focus on my workout and get on with my day comfortably!
The invisible scrunch is my favourite feature. It gives the bum a great shape without that obvious, prominent scrunch line you see on so many other leggings. Such a flattering, comfortable fit without compromising on style. Definitely a winner! ❤️
The shorts look and feel amazing. They give great shape and a smoothing effect along the stomach.
Cute! Probably the only bike shorts I’ve ever bought that don’t cut into my legs but I still probably should have sized up. Fabric is super comfy and squat proof!
i love the colour an how it is squat proof
Wayyyyyy too small
Great shorts!
These are very comfortable and I will definitely be buying more
Super comfy gym shorts, best in my experience for pilates due to the very light fabric. I prefer a high compression for high intensity exercises
So good. Great length and fit and I love the colour
Super comfy and great colour
Beauriful colour, first time not buying black. Totally worth it, love the quality and fit.
Fabric feels great and I feel so confident and comfortable wearing these. I usually go for black but these are really flattering on!
