Pharrell Williams wants his own concept store.

The 'Happy' hitmaker has been considering opening a fashion emporium in Miami and already knows exactly what his future shop would stock.

He speculated in an interview with ''A concept store like [Paris'] Colette in Miami could be cool. I don't know what the best location would be. Perhaps Lincoln Road or even Bayside...

''Inside, you'd find lots of products imported from Europe as well as my own collections. I would have a whole floor dedicated to hats and caps, I can't get enough of them.''

Pharrell is concentrating on his fashion collaborations for now, including his recent 'I am OTHER' line for Japanese brand Uniqlo.

He explained: ''I like Uniqlo's simplicity. I created a capsule collection of T-shirts and caps to help celebrate their twelfth birthday. The design is very clean, that's what I love.''

The trend-setting star has definitely made his mark on Hollywood with his funky style, with the Vivienne Westwood Buffalo hat he wore to the Grammy Awards becoming a worldwide phenomenon, raising $44,100 in a charity auction benefitting his charity One Hand to Another.

Asked what his next move was going to be, he told the French website: ''Maybe a top hat... I love clothes and I only do what I'm passionate about. I love making a scene when I turn up on the red carpet in shorts.''
