Vancouver in 1 month, how can I look my best?

turningheads2012

Hey
So I'm going to Vancouver in one month exactly and I would LOVE to be able to look my best. I'm seeing one of my dad's friend who I haven't seen since I was about 13 - and I'm turning 20 this July.
I've been able to maintain my weight around 112-116 lbs. I'm only 5'2.
I would love to be able to hit below 110 lbs (the healthy way) by eating really only fruits, veggies, nuts, beans, yogurt, soy milk. (with a few extras here and threre)
What do you think would be the most reasonable weight I could obtain by June 1st ?
I also go to hot yoga once a week, and try to get to the gym 4-5 time a week for at least an hour ( lots of cardio, with some ab/arm exercizes at the end )

Any help is appreciated ! xo

PS: If your going to hate on me for wanting to lose weight, don't bother commenting. I'm not going to be unhealthy by going under 110 lbs.
