One Piece. Every Occasion. No Effort Required.

Easy, elegant, and endlessly wearable — Harriet is the jumpsuit that takes the guesswork out of getting dressed. Cut in a relaxed, loose silhouette with a sleeveless design, she moves with you throughout the day without sacrificing a polished, put-together finish.

Whether dressed up with heels or paired with sandals for a casual day out, Harriet brings an effortless sensibility to every occasion. Available in three versatile colourways that work across every season.

WHY WOMEN LOVE IT

  • Relaxed Loose Fit: The generously cut silhouette provides all-day ease and comfort, draping beautifully on the body without any clinginess or restriction.
  • Sleeveless Design: A clean, unfussy sleeveless cut keeps Harriet cool and breathable during warmer months while remaining effortlessly stylish year-round.
  • Versatile Colourways: Available in Black, Khaki, and Green — three easy-to-wear tones that pair beautifully with sandals, trainers, heels, and statement jewellery alike.
  • One-Piece Simplicity: No outfit coordination required. Harriet goes from hanger to door in seconds, making her ideal for busy mornings and last-minute plans.
  • Relaxed but Refined: The clean lines and quality drape give Harriet a composed, smart look that works just as well at a summer garden party as it does on a weekend away.

Dress it up, dress it down — Harriet has every occasion covered.

THE HARTLEY SISTERS

Some dreams start with two sisters and a crazy idea. ✨

This year, we're celebrating our very first anniversary. 🤍

To say thank you, we're running our Hartley Sisters Summer Sale with discounts of up to 60%. Our little way of saying thank you for supporting two sisters building something from the heart.

WHAT CUSTOMERS SAY ABOUT US

I wore my new dress to lunch with friends and they all asked where it was from. It fits beautifully and makes me feel stylish without trying too hard.

I was hesitant to order online at first, but the whole experience was completely stress free. The item arrived exactly as shown and the fabric feels lovely on the skin.

I had fallen into the habit of wearing the same outfits every week. This piece made me feel elegant and confident again. The quality is so much better than I expected for the price.

Practical and elegant at the same time. Perfect for chilly British mornings. I have already ordered two more pieces.

The clothes fit perfectly and the quality is genuinely impressive. The Hartley SIsters has become my go-to store for elegant everyday pieces.
