Will I have loose skin after I lose 60 lbs?

inhave always been a big girl, but in the past two years at uni i have gained so much weight. Even thought i have gained a lot of weight all of a sudden i am lucky i dont have many stretch marks. I want to lose 60 lbs, maybe a little less, but i am worried about the loose skin. What are your personal experiences on weightloss and loose skin?
