So in love with this top- I am actually going to wear it as a bikini on the beach. The softest highest quality material and the cutest design!

Material is amazingly soft and the colour is incredible. I ordered 2 sizes larger than I normally do not the best sizing situation - I’m normally a M and according to measurements on the sizing chart I ordered XL. Fortunately it worked out for me but yeah maybe consider more inclusive sizing for different bodies?

Love this fabric! I prefer the fit of the other thong style but a great product.

Love the fabric and nice to have colour options when most low tox products are neutrals. Feel great on.

Amazing quality and fits so well. I was really surprised how comfortable the bras are, usually I am so aware of the elastic support, but I hardly notice it with this bra. Very good design.

Absolutely love this bodysuit, great cut and perfect for the sauna! I'm glad I went up a size to a Large (I'm usually a Medium) so it's super comfortable. Please don't discontinue this!

as always, the quality and comfort of the fabric is amazing, these are my favourite undies. The new colours are lovely but I couldn't buy the more popular ones because of sold out. I had the first first colours so I wanted to obviously keep buying this brand next ones.
I do think the previous elastic band colour which was grey with the brand name in black was more appealing and had a more serious cool and interesting look, it contrasted much better with different colours. For me at least it was more calling.... hihihi

Anyways, keep on producing them. they last long and the fabric is super comfy and doesn't flatten your butt, it makes it look nice!

I bought one of these to try and liked it so much I ordered two more. They’re super cute, comfortable, and feel great on. So soft! Love this racerback style. I’m a 34A/10A but usually size up because I don’t like a tight bra. The size L is perfect - not too tight/no riding up. I feel like I finally found the perfect bra after literally decades of looking.
