Two Sisters. One Final Season.
After 27 years, we're closing.
We're Lucy and Emma. We built this boutique on one principle: only sell pieces made properly.
Hand-finished seams. Construction that lasts years, not months.
But our supply chain is disappearing. Workshops closing. Artisans retiring.
Meanwhile, fast fashion brands drop hundreds of styles weekly. Made fast. Made cheap.
We can't compete. And we won't compromise.
This is our final collection.
