Judging by those erect nipples Julia Stiles is sporting in this pic, the sea she’s exiting was rather cold. That’s the one good thing about cold water on a hot day at the beach – it turns normal nipples into erect nipples and that’s never a bad outcome. Especially if the nips get so hard they poke through the thin material of a bikini top and leave little to the imagination. Hurrah for cold water!
