Much like a puff sleeve, a collar on a dress (especially one of the Peter Pan type) gives your festive one-piece that je ne sais quoi that few other details can provide. Few smocked dresses of yesteryear were without one, and while I'm no longer reaching for looks that are quite so juvenile, I can't help my love for that extraspecial finish around the necklines of my minis.
