Holy sheer. Leaving little to the imagination, Dancing With the Stars' Julianne Hough turned heads in a super see-through dress at the Us Weekly Hot Hollywood Party in LA last night (April 18).

The blond babe donned a maroon long-sleeve dress with pieces of dark fabric partially covering her naughty areas — a look we're sure her boyfriend Ryan Seacrest was a fan of.

While Julianne isn't currently on DWTS Season 14, the former pro is clearly keeping busy, with starring roles in both Footloose and the upcoming Rock of Ages (hitting theaters on June 15, 2012).

Dancing With the Stars airs Mondays and Tuesdays on ABC.
