Petite isn't about size but rather proportions. The petite section will have all of the regular sizes. There are even plus petites.I am of no way any help but a funny thing came to mind! Everytime Im out shopping and I accidently wonder into the petite section, as soon as I realize I try and walk out ASAP as I dont want someone to think Im all trying to act like Im petite or something!!!! (Im a size 10!!) I WISH I could shop in the petites!!! Good luck!! I saw LOTS AND LOTS of 0 in Banana republic!!
