How to measure

- Waist. Around the narrowest part, usually just above the navel.
- Hips. Around the fullest part, standing with your feet together.
The length varies by style: you will find it in the product description. If you are between two sizes, take the larger one.

The dress that needs nothing else. Berta is satin, floor length, with a deep V-neck that ties at the neck and leaves the whole back bare. Down one side a cascading ruffle falls right over the slit.
The waist is draped and fitted, and from there the skirt opens out. That contrast — close to the body above, full below — is what lengthens the line, and the side ruffle breaks the vertical so it is not just another long dress. At the neckline a gold fitting holds the strap and finishes the whole thing off.
It is an evening dress and it makes no secret of it: deep neckline, bare back and a high slit. If you want something covered for a daytime ceremony or a religious wedding, this is not your dress.
Key Details
Deep V-neck: with a halter neck that ties at the nape.
Bare back: open to the waist.
Gold fitting: at the neckline, it holds the strap and doubles as jewellery.
Draped waist: the gathering marks the middle and skims the tummy.
Cascading ruffle: it runs down the side and falls over the slit.
High leg slit: it opens as you walk and disappears when you stop.
Satin with drape: it catches the light and moves with you.
Floor length: designed to be worn with heels.
Five colours: black, red, blue, pink and yellow.
Perfect for: an evening wedding, a gala, black-tie cocktails and New Year's Eve.
What to wear underneath
It takes no bra: there are no straps to cover one and no back to hook it to. Adhesives or fashion tape work perfectly, and the draping at the waist helps make sure nothing shows.
Size guide
It is close from bust to hip, so it does not forgive the way a loose dress does. If you are between two sizes, take the larger one: satin shows everything and it is easier to take in than to let out.
The supplier has not given us a measurement chart for this piece and we do not want to invent one. Write to us on Instagram with your bust, waist and hip measurements and we will tell you your size before you buy.
Colour may vary slightly depending on the lighting in the photographs.
