Sims 3 Town Life Comes with 2 New Hairstyles for Women, 1 for Men, and 1 each of the same haircut for children. Nothing for toddlers.
Sims 3 Town Life also comes with a variety of new Clothing as you will see below, but again, nothing included for toddlers and no clothing for Teens. There are not any new shoes & no new accessories.
This ought to hold you for now..next up I will grab screens of the new Venues & Objects in Town!
