Which should i buy?? ?

Neither - and, please, tell your mother, from me, that you are at least five years too old for baby-wear. The panties, in the link provided, are inexpensive enough but somewhat more suitable for your age - by next year, I ume you will be permitted to have adult underwear! Be sure to check the size chart on upper right of page - I doubt these will shrink much at all so get the ones that are your hip size.
