8 Marilyn Monroe Costume Ideas to Make You the Absolute Star of Halloween

Marilyn’s iconic red dress from the movie Niagara is the perfect way to channel her famous curves. This vintage-inspired wiggle dress, a popular silhouette in the ’50s and ’60s (and, as the name suggests, encourages a daintier walk due to its slimmer bias), will have you feeling like a total Old Hollywood screen siren. We also found a Halloween costume version as an additional option.

Have your eye on the costume contest? There’s no competition with this gilded ensemble that’s based on another scene from Gentleman Prefer Blondes. Add a white faux-fur stole to your Marilyn Monroe costume to keep warm on a cool October night.

We also found a costume version of the look for those who want a no-brainer.
