Aw. Our little boy is growing up. Tween sensation Justin Bieber is really showing off his love of designer duds these days. Why just this morning the little millionaire wore a Fair Isle patterned varsity jacket from Junya Watanabe's covetable fall show--which only set him back a mere $1,650--on NBC's 'Today' show this morning. If you'd like to copy the Bieb's collegiate moment (which, by the way, is oh-so-trendy right now) you can grab the jacket at MR PORTER right now--before it sells out.
