Santorini Summer Dress — Adjustable-Strap Midi
Inspired by long afternoons in white-washed Cycladic villages, the Santorini Dress brings effortless Mediterranean style to wherever you happen to be.
The fluid silhouette skims the body without clinging. The adjustable straps mean you can dial in the perfect fit, whether you're a long torso or a shorter one. And the soft V-neckline strikes the balance between elegant and easy.

It's the dress that does everything. Wear it to a sunset beer garden with sandals. Pack it for a Greek island week. Dress it up for an outdoor summer wedding with heels and a delicate gold chain. The fabric is breathable, the cut is forgiving, and you'll feel like the holiday version of yourself every time you put it on.
Fully lined. Machine washable. Holiday essential.

FAQ
Is it lined? Yes — the dress is fully lined for comfort and opacity.
What bra works underneath? A stick-on or strapless bra works best. The adjustable straps allow a regular bra strap to be hidden if you adjust them outwards.
Is it suitable as a wedding guest dress? Yes — perfect for outdoor, garden, or seaside weddings. We recommend dressing it up with heels and a delicate necklace.
True to size? Yes, with a generous fit. If between sizes, size down.
Does it wrinkle in a suitcase? Minimally — it packs flat and any creasing drops out when hung.
UK delivery? 4–7 working days. Free over £35. Free returns within 14 days.
At DKAI London, every piece is designed with the British wardrobe in mind — real bodies, real lifestyles, no compromise on fit. Our sizing follows standard UK measurements, so the size you wear from M&S, Next, or & Other Stories should fit you here too.

How to Measure Yourself
For the most accurate fit, use a soft tape measure and wear well-fitting underwear. Stand naturally — don't suck in or stretch up.
- Bust / Chest: Measure around the fullest part, tape parallel to the floor.
- Waist: Measure around your natural waist — the narrowest point, usually about 2.5 cm (1") above your belly button.
- Hips: Measure around the fullest part of your hips, usually 18-20 cm (7-8") below your waist.
- Inseam (for trousers): Measure from your crotch to your ankle bone, along the inside of your leg.
