I would assume that Barbie was influenced by Twiggy's looks, but Barbie was introduced in 1959. Twiggy didnt debut til the 60's. I guess it doesnt matter; they're both beautiful.
Speaking of Barbie, wouldn't be cool if u could really have her clothes. I used to wish for that when i was younger. Just give me all of her clothes and i'll be great! lol. So let's make dreams come true - here's a video of the Barbie Fashion Show 2009:
You can see the whole show here.
ENJOY! -Allie ;)
