Glasgow-based Oh Polly is known for its figure-hugging dresses and skimpy swimwear, which it says are designed “for girls, by girls”. The business was started in 2015 by Claire Henderson, 30, and Mike Branney, 32, who were studying engineering. Its quirkily named clothes — from a “Tie Me A River” dress to a “Just Beachy” bikini — have made it a hit in Ireland, Australia and America, helping international sales double to an annualised £3.8m last year. In July, it opened an office in Los Angeles to produce curated content for its 2m Instagram followers.
