Skeptical at first with online purchases. But absolutely stunning dresses and tops! Not the cheapest, but worth it!
First time shopping with you and I'm over the moon! Amazing dress and a lovely handwritten note. Made my day xx
It really is so comfortable and airy, finally!! Been looking for something like this forever.. You will be seeing me again
What a find. Wonderfull team, beautiful dresses and such a great boutique. This is my go-to since I discovered it. Thanks

Most tank tops make you choose: comfortable or put-together. Marnie doesn't make you choose.
Soft enough to wear all day. Flattering enough to wear out. Built-in support that actually works — no separate bra, no readjusting, no compromises. Just pop it on and get on with your day.
✔ Buttery-soft cotton-nylon blend — lightweight, breathable and moves with you
✔ Built-in bra with strategically placed padding — stays perfectly in position, wash after wash
✔ Support stops at your sides, not your back — zero visible lines, nothing digging in
✔ Smooth compression fit — skims without clinging, flatters without squeezing
✔ Machine wash cold, tumble dry low — no special care, just wear it
Note: the fit runs fitted, so if you're between sizes, size up.
