The Horizon Stripe Maxi Dress is a full-length organza dress from London label Sister Jane, in a bold black and white stripe. A statement occasion piece that doesn't rely on embellishment to do the work.

Cut to maxi length in a crisp striped organza that holds its shape and moves with air through it. An adjustable necktie sits at the throat and the front fastens with gem buttons. Partially lined, and finished with a contrast faux suede belt to draw in the waist.

Fit and sizing: full-length with a belted waist. Available in sizes XS to M.

Care: Specialist clean only. Organza creases easily — hang rather than fold.

How to wear it: as it comes for a wedding or a race day, belt on and necktie tied. For something less formal, leave the tie loose and add a flat boot. The graphic stripe means jewellery can stay simple.
