There's a sense of ease in a dress that drapes so effortlessly. Sietske is designed for days when you want to wear something beautiful without giving it a second thought. With its relaxed cut, V-neck, and charming button details, it offers the perfect balance between casual and polished. The flowing sleeves add a soft touch.

You can wear it effortlessly for a sunny beach walk, a weekend brunch, or a summer city trip.

Sietske | Breezy Button-Front Midi Dress in Green

Why you'll wear it

  • Easy care: the wrinkle-resistant material makes this the perfect suitcase favorite.
  • Breathable comfort: the loose fit offers maximum freedom of movement on warm days.
  • Refined details: the button closure and subtle pleat create a flattering line.
  • Flowing sleeves: the three-quarter-length sleeves with ruffles feel wonderfully summery.

Sietske | Breezy Button-Front Midi Dress in Blue

Fit and fabric

Sietske is made from lightweight, fluid polyester that feels soft to the touch. The dress has a relaxed fit that doesn't cling anywhere. Thanks to the pleat beneath the button placket, the fabric has extra room, creating an elegant drape at the knee.

Pair it with a straw bag and sandals for the beach, or wear it with espadrilles for a day in the city.

My coat still looks like it did on day one after three winters. That’s exactly what you buy from Sarah & Kate.

No disposable fashion. My knitted sweater is timeless and high-quality; I reach for it every autumn.

Very good quality for a fair price. The trousers have a slightly looser fit: simply order one size smaller and they will fit perfectly.
