One Piece. Zero Effort. Maximum Elegance.

The smocked square neck jumpsuit works because it solves a real problem: looking put-together without the effort of coordinating separates. The smocked bodice shapes and holds without being restrictive, the square neckline frames the collarbone beautifully, and the wide leg creates a flowy silhouette that photographs well and moves even better. Long sleeves make it a year-round piece, not just a summer one. Available in multiple colours in UK sizes XS to 2XL.


Why You’ll Love It

Smocked bodice — shapes and supports while staying comfortable for all-day wear
Square neckline — flatters and accentuates the collarbone; elegant without being revealing
Wide leg silhouette — flowy and feminine, creates an elongated leg line that photographs beautifully
Long sleeves — makes this a year-round piece, not season-limited
One piece ease — no coordination needed; add accessories and go
100% polyester — smooth drape, easy care, holds colour wash after wash

How to Style

A solid colour jumpsuit is a blank canvas for accessories. A bold belt at the waist to accentuate the smocking, heeled mules or block heels for occasion wear, or simple trainers for a dressed-down day look — all work. Add a blazer over the top for a smart-casual office-ready version. For jumpsuit styling ideas, Vogue UK’s guide to styling a jumpsuit and Who What Wear UK on wide leg jumpsuit outfits are worth a look.

1
Occasion ready — Jumpsuit + heeled mules + gold jewellery + clutch bag
2
Smart casual — Jumpsuit + fitted blazer + block-heel boots
3
Casual day — Jumpsuit + white trainers + tote bag — the wide leg and smocking keep it elevated

Frequently Asked Questions

Can I wear this as eveningwear? +

Yes — the square neckline and wide leg silhouette translate well to evening wear. Style with heeled sandals, jewellery, and a clutch for a restaurant dinner or cocktail event. Black and deeper colourways work particularly well for evenings.

How do I size for the smocked bodice? +

The smocked bodice has low stretch, so measure your bust and waist and check the size cards below. The smocking provides a little give, but we recommend sizing up if you’re between sizes for a more comfortable fit across the bodice.

Is the wide leg very long? +

The jumpsuit has a full-length leg with approximately 69cm (27.2") inseam in size S. This is designed for heels, but the wide leg also looks great floor-grazing with flat sandals for a relaxed boho feel.

What colours is this available in? +

This jumpsuit comes in multiple colourways — select from the colour options above the Add to Bag button. Each colourway shares the same smocked square neck design and wide leg silhouette.
