Sheer detailing and paneling on dresses is hot for 2012, but there is a thin line between looking like a sheer genius or a sheer terror. Sheer isn’t about looking half naked, it’s about subtle sexy, like Zoe Saldana’s gown. Black is an easy way to execute the trend but greys, greens and dark blues can also keep it interesting. Whatever you do: always wear undergarments! Skin colored or black lingerie will help keep you covered without looking completely obvious.
