The White Company is set to enter the US market with a store on New York’s Fifth Avenue opening this summer.
There are plans to open more stores in malls across New York state, New Jersey and Connecticut.
The retailer reported “significant growth” in the second year of its US ecommerce business in its last full-year.
It unveiled surging profits against strong comparables despite a “difficult trading environment”.
Pre-tax profits, excluding exceptional items, were up 50% to £17.2m in its full-year to March 26.
Sales rose 12.6% to £184.3m in the 12 months, during which the retailer opened two new stores in Meadowhall, Sheffield, and Birmingham. It now has 56 stores across the UK.
Boss Will Kernan departed for specialist sports retailer Wiggle last month, replacing Stefan Barden at the helm.
