At Von Dutch, he increased global sales of adult clothing from US$5 million to US$50 million [£2.5 million to£25 million] in three years, helping to establish the iconic US company as an international brand.

Juul said: 'I see an exciting opportunity to boost the presence of a label that dares to be different and is as cutting edge as it was in its original form, back in Australia in 1969.'
Richard Ratner, analyst at Hot Tuna's house broker Seymour Pierce, said: 'This is a very good appointment for Hot Tuna and follows recent news of major orders.'
The surf brand is to open its first London flagship store this year, as it moves into retail following its AIM float in 2005.
Hot Tuna has headquarters in the UK, USA, and the brand's homeland of Australia.
