You've got a nice enough facial structure that either up or down will work. I vote down. If you're looking to impress your date,
definitely down. Female friends will encourage the "up" look, which is supposedly more sophisticated - it just isn't as feminine. Seriously, it isn't. It all depends on your target audience - a lot of girls are going to have their hair up, ala Oscar ceremonies. Jennifer Lopez with hair up - too hard-edged
