Dresses — cocoon maxi dress
Pull it on and you are dressed
A cocoon-cut maxi dress in a lightweight cotton and polyester blend, with a round neck and three-quarter sleeves, falling loosely from shoulder to ankle.

Cocoon shape
The dress falls away from the body instead of clinging, so there is nothing to adjust as you move.
Round neckline
Plain and simple, it works on its own or under a cardigan, and leaves room for a necklace.
Three-quarter sleeves
They stop below the elbow and give the arms light coverage.
Cut for L to 5XL
The dress is offered from L to 5XL and cut generously across the whole range.
Because the cocoon shape falls away from the body, the look does not depend on hitting your measurements exactly.


A hem that reaches the ankle
The skirt drops to a maxi length close to the ankle, which keeps the long, flowing line of the cocoon shape.
Flat sandals suit it in warm weather; boots and a belt at the waist change the outline when it turns cooler.
Styling
How to wear it
Wear it with flat sandals in warm weather, or with boots and a belt at the waist.
A cardigan over the top carries it into cooler days, and the round neck leaves space for a scarf or a long chain.

The fit is loose and falls freely over the body, so take your usual size and let the cocoon cut do the rest. The model is 5ft 7 and wears a size L.

Store offer
Buy two, save 10%. Buy three or more, save 15%.
The saving is applied automatically at checkout, so there is no code to type in. The pieces do not have to match — any two items in the basket count, and the discount reflects what you actually pay if you later return part of the order.
High demand
The size you want may not wait
We are sending a lot of traffic to this dress, and sizes do not sell evenly — the middle of the range empties first. A colour that is here today is not guaranteed to be here when you come back to it.
Nothing is held for you in a basket. If your size is selectable above, that is the moment to take it.
Before you go
Check the size guide above before you choose. It is measured from the garment itself, laid flat, not from a standard size chart.
Orders are handed to the carrier within one to three working days of payment, and standard delivery is free on every order.

Our pieces follow UK sizing. Every product page shows its measurements when available.
