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!

I love the rust colour, it's very flattering to my skin tone, and the fit is so comfy that I have to keep checking that everything is where it's meant to be because I can't feel any uncomfortable pressure points. Will continue to get this one going forward.

Very well made, washes well and is comfortable. However the gusset is too short, wish it would come up higher!

It’s perfect for sauna and the fit is really nice too

Absolutely love this bralette, I was worried the knot at the back would be annoying under tight tops but it’s not.
I really like that I can adjust it as I want and need, it’s beautiful, soft and washed really well.
I’ve had 4 pairs now and loved them all.

Fantastic! Great quality. I sauna every day and love the 100 % cotton fabric, so comfortable and the darker colour means it isnt transparent. Would love other dark colour options too !
