Replying to Orage Clothing For my size

ok well since the prices are low im looking for some new orage clothing for next season. I am looking at the Carnaby Jacket and matching Noho pants. Im 5'4 and about 115 pounds and 14 so im about average size. I dont have any extraodinarly long limbs or anything so i was wondering what sizes i should get and wear i could get em? I really like the style but if anyone else has any really sick ideas that would be awesome too. thanks
