The holidays often call for "ugly" sweaters (or as the English politely put it, "Christmas jumpers") and matching outfits with your siblings. It's a season of festive garb you'll likely regret years later, yet not one that excludes our favorite celebrities.

Both Kristen Wiig and Julia Roberts opted for a suiting at their big movie premieres (for The Secret Life of Walter Mitty and August: Osage County, respectively) yet both failed to find that necessary balance between sexy-oversized and frumpy. While Justin Bieber wore a red Balmain suit to celebrate the release of his new movie, Believe, pop starlet Jessica Jarrell went a step further by showing some skin in super-tight leather. (Easy now. There are kids around.)

From uninspired menswear, to too much skin and problematic plaids, stars were not immune to fashion don'ts over the past two weeks. Check out the worst look inside.
