Sienna | Cut-Out Waist Maxi Dress

Effortlessly chic, the Sienna is designed for women who move through the world with ease. A fitted spaghetti-strap bodice with a signature cut-out waist detail flows into a full, billowing skirt — striking the perfect balance between sleek and relaxed.

The open back with a delicate tie closure adds a touch of allure, while the lightweight fabric drapes beautifully and catches the breeze. Style Sienna with strappy sandals and gold jewellery for a look that works from a seaside promenade to a Parisian café terrace.

Available in Black, Beige, Dark Brown, and Olive Green.

Spaghetti straps · Cut-out waist · Open tie-back · Full maxi skirt · Side pockets

So easy to dress up

Website
Laura M. Verified buyer

I love this jumpsuit. The fabric falls really nicely and the wide legs make it look elegant without feeling too formal.

Very flattering

Website
Sophie K. Verified buyer

The waist detail is beautiful and gives a nice shape. I wore it with gold jewellery and heels and felt really confident.

Perfect holiday outfit

E-mail
Emma R. Verified buyer

This is exactly the kind of piece I like for summer evenings. Comfortable, light and still looks dressed up.

Love the open back

Website
Claire B. Verified buyer

The tie back is such a pretty detail. It feels feminine but still classy. Also love that it has pockets.

Better than expected

Website
Nina S. Verified buyer

I was surprised by how nice it looked on. The top fits well and the trousers have a lovely flow when walking.

Chic and comfortable

Website
Rachel T. Verified buyer

Really happy with this one. It looks stylish but I didn’t feel restricted at all, which is rare with jumpsuits.

Beautiful but long

E-mail
Hannah L. Verified buyer

Gorgeous jumpsuit and very flattering, but the legs are a little long on me. With heels it is fine.

Nice Fit

Website
Maria V. Verified buyer

The fit is lovely and the black colour is very classy. I did need to adjust the straps a bit to make it sit right.

Pretty for evenings

Website
Julia P. Verified buyer

Really nice for dinner or vacation. The back detail is beautiful, only thing is you need the right bra or no bra with it.

Nice but not perfect

E-mail
Megan C. Verified buyer

It looks pretty, but the top didn’t fit me as well as I hoped. The trousers are lovely though.

Our Story

"We built it for the woman who already knows who she is — and just needs clothes that keep up with her."

We're Hannah and William. 15 years ago we met at an industry event and argued about fabrics for an hour. That argument never really stopped — and neither did our obsession with getting it right.

Every piece in our boutique is chosen with one question: Will a woman feel beautiful in this? Will it hold up through her actual life?

— Hannah & William

"I bought this dress for a small anniversary dinner and honestly loved everything about it. The pleated skirt gives it movement without feeling overly dressy, and the top part fits in such a clean, flattering way."

"I first didn’t think this dress would make me feel confident enough to actually wear it out, but I was so wrong. The moment I put it on, I felt amazing and walked outside feeling more confident than I have in a long time."
