Muscly Andy Murray likes tight shirt, not short shorts

An increasingly muscular Andy Murray Thursday said he's comfortable playing in his new tight shirt, but draws the line at 1980s-style short shorts.

Murray's bulked-up physique has attracted comments at the Australian Open, but he insisted it's the new fitted shirt which is making his upper body look bigger.

However, the US Open champion, patiently answering questions about his sartorial choices, said a tight shirt was better than baggy, especially in hot temperatures of Melbourne.

"The only thing I don't like on shirts is if they come down too low and sometimes your elbows can get caught in the shirt," he said.

"The less material there is on the shirt I think probably the better. There's less to get in the way. But so long as they're tailored somewhat, I think there's no real problem."

Murray also said he could not see himself wearing the type of shorter shorts worn by his coach Ivan Lendl in his playing days in the 1980s.

"I actually wore a pair at Wimbledon when I was with Fred Perry that were short," he said.

"Not quite like what Ivan and those guys used to wear on the court. I can't see a return to them, to be honest.

"Yeah, they were a bit too short. Didn't leave too much to the imagination."

Murray is not the only player sporting a new look at the Australian Open, with Roger Federer wearing bright pink laces for his second-round match against Nikolay Davydenko.
