Most Helpful Guy
OK, if you want attention:
Extra high heels, for one thing. In a bold color.
A clingy dresss that flatters your figure without being too garish. You don't want to look desperate, so make sure you're not showing a lot of cleavage and he dress shouldn't be short or too tight.
I'll leave the hair up to you, it's too hard to give advice about that without a picture..but don't try to redo your hair completely, it will look like you're trying to attract another guy. Plus, you want everyone to recognize you!
Wear a contrasting scarf or top, again, to get people's attention.
Keept he akeup light, again, you don't want to look like you're cruising for a new guy.
A trendy hat would top off the ensemble.
Don't go up to him, make him come to you!
