Where did my brother go?.. help!! Points for right answer!!!?

My brother left home today at noon, wearing a suit.

Here's what I do know,
1. He's an adult, has a car, job etc... and is in his mid 20's.
2. It's not an interview of any sort.
3. It's Saturday afternoon.
4. He doesn't wear a full suit to work, just dress clothes.

Help!
I'm supposed to call him in 20 minutes when I figure it out. But I'm out of ideas.
