PITTSBURGH — The “Normal Barbie” is now available for purchase, and children can soon add stretch marks, acne and a touch of cellulite to their dolls. Last year, Nickolay Lamm created the Lammily Doll to mirror the average 19-year-old girl’s measurements as taken by the Center for Disease Control. Lamm wanted to create a doll that would teach children what women actually looked like, so he digitally designed a doll that represented a woman who is 5-feet 4-inches and 165 pounds.
