For further research I looked into big name brands that have gone bust, I found a website that talked about Bhs and other big names going bust this year and came across an excel spreadsheet with a list of who has gone bust or administration. I have highlighted the only sportswear company on the list.
This for me shows further that it is very competitive on the high street and for Hotstar to make a real go of it the brand needs to be unique and bring something to the market that is missing, Under Armour are a success because they designed a great material for sportswear which was a need for the market.
