Best Bet: Banana Republic Collar Necklace

With sparkling stones set in neat circular rows, this crystal collar is just unusual enough to dress up almost any casual outfit. Imagine it peeking out from under a chambray button-up, or serving as the crowning touch to a classic crew-neck knit. Or wear it to complement your décolletage with a shoulder-less cocktail dress on a fancier occasion.

Banana Republic Crystal Collar Necklace, $80 at Banana Republic.
