  • Modest, comfort-fit shorts
  • Tummy-skimming silhouette
  • Quick-dry, breathable polyester
  • True sizing (S-2XL)

Confidence & comfort — from the moment you put it on.

Hassle-free size exchange
I originally ordered a medium, but it came up a bit small round the waist. I got in touch with customer service and they swapped it for a large within two days, with no extra postage to pay. Brilliant service!

Pastel shades don't always come across properly in online photos, so I was a bit wary. But in real life the colour is spot on – exactly as it looks in the pictures.

Absolutely delighted with my order! The jacket is beautiful: the floral print is even lovelier in person, and the fleece lining makes it wonderfully cosy. The whole process was smooth from start to finish. Would happily order again. Highly recommended!

OUR STORY

SHE OPENED THE DOORS. WE NEVER THOUGHT WE’D CLOSE THEM.

This is the last photo we have with our mother in the shop.

She opened this boutique in 1988 and chose every blouse and dress herself. Her taste was in the windows, on the rails, in every little detail.

After we lost her, we kept going. We were her daughters before we became shopkeepers, and keeping her doors open was our way of holding on.

But rising costs and quieter seasons have brought us to our hardest decision: Hetty London is closing.

Before we turn the key one last time, we’re offering our remaining collection in our final sale.

We’re keeping this photograph. We hope you’ll find a piece you’ll want to keep, too.
