Chances of getting accepted to FIT + Portfolio tips

<p>I'm a high school senior, and I'm currently applying to FIT for fashion design. I just want to know what my chances are of getting in.
I've been taking almost all honors classes since freshman year, with 2 AP classes last year, and 1 AP class now.My gpa is about a 3.7. I participated in a major school play as a costume leader, making all the costumes (last year and will do it again this year). I've been taking pre-college courses at FIT for 2 years. My sketches are stronger than my sewing skills.
Also, any tips for portfolio preparation?</p>
