High quality and super impressed
The material is incredibly soft and moulds to your skin beautifully so that it feels weightless and leaves your movement unlimited. The clever design means the top always feels secure in place and so you can get on with your workout without constantly worrying about adjusting or slippage!

I like the design though xs is a bit too big. Maybe there could be more compression. Colour and design is great. It looks very flattering.

Tiny
They were very small for their size, and they seaming pulled in transit. For the price point they could have been made better. I feel this brand is only meant for the skinny folks 😕

Can't believe it's £20
Still can't believe this is £20. I get so many compliments when I wear this. It's my favourite thing in the wardrobe atm.
A change for the worse..
The fit is just not it anymore. Bought this exact top 2-3 years ago in one of the original colors and the fit was just perfect. The material was thick and it had a nice compression. Don’t know what happened but some time back the material in the timeless collection changed. It’s still comfortable and smooth but it’s much thinner and lacks the compression it once had. This is especially clear when it comes to the long sleeve top as the fit is much different, e.g., saggy in the back. Really disappointed by this change.

The most perfect top
This top is sooo beautiful. I own every colour! I sized up to a medium and wear the curved bra underneath when I want more coverage. So soft and comfy.

Stays in place!
The only headband that stays in place! I went on a 2 mile run and it didn’t budge!
It is not favourite...
It is not favourite leggings since there isnt that much of compression. Seems quite secure from the bottom until thighs, though hips and bum arent as supported. I think I prefer timeless leggings material. Colour is lovely and details looks nice.

Great quality as always
Lovely leggings but unfortunately too short in the leg for me as I’m 5 foot 8.
Love the color and material
I really love this bra! The reason I gave it 4 stars is I would love to have the choice of padding to remove or keep in since sometimes my girls show when its cold! Otherwise I love the material and it moves well with me.
Love it.
