Rachel Weisz’s messy faux bob is so carefree and fun, perfect if you want to casually show off your shoulders. It’s so sexy and refreshing to see loose layers that fall just below the chin, and this also draws attention first to your collarbones and then down to your dress. Try parting your hair to the side for a flirter vibe, or down the middle if you want to keep it casual. You can also pair this look with a sparkly necklace to make your casual gown a bit more elegant.
