I must say I suprised myself when I seriously thought would want Onepiece.
Of course when I first time saw those I was like "why ever someone would buy that with over 200 euros?". Still I'm not ready to pay 200 euros just one jumpsuit when I can buy much cheaper one. Friend of mine said one day it's comfortable under the jacket when you're snowboarding and I think it might be true. I do snowboard so that's why I would want onepiece someday - not the reason I can wear it to school (someones do that and I think it's not very cool).
