What does it means if a guy asks about clothing advice?

Anonymous
So I was talking to a guy on Skype, and we are pretty close but we've been like on and off in like a year now. And we flirt and tease each other. But he asked me which tshirt is the best and at the moment I didn't think about it. But when his friend was with us one time, I asked if he bought the shirt and the friend was like surprised that he'd asked me for advice about clothes. Does it mean something? I didn't get why he was so surprised...
