With Topshop having had such raging success in the States - Beyonce just can't stop wearing it - Primark bosses are hoping to recreate the magic with a new 70,000 sq-ft store, set to open in Boston at the end of 2015.
The hype has even led bookies Paddy Power to offer odds on a Primark collaboration with Kanye West (33/1 - can you even imagine?), while bets on Michelle Obama wearing a Primark twin-set are currently 7/2.
There are concerns that the Primarni appeal might not grab Americans in quite the same way however, with the bookmakers also offering 4/1 odds on the Boston Primark store permanently closing its doors by 2016.
So what do you think? Will Primark succeed where M&S and Tesco failed?
