Kristen Wiig delivered a serious style gaffe upon arriving at Thursday evening’s “Portlandia” Season 2 premiere party.The “Bridesmaids” star/scribe looked sloppy from head to toe with her unkempt bun, cream-colored capelet, animal print blouse, high-waisted trousers, and brown boots. Hopefully the fashion-challenged funny lady will hire a stylist by January 15 because we wouldn’t want her dressing herself for the 69th Annual Golden Globes! …

Speaking of style missteps, check out the chintzy-looking Tom Ford frock and ringlet-adorned ‘do Rihanna unsuccessfully rocked while partying with P. Diddy in Miami on New Year’s Eve.

Following in Kim’s footsteps was her absurdly dressed mother, Kris Jenner, who — for some unknown reason — has a penchant for wearing maitre d’-inspired ensembles.

Perhaps it’s just us, but it seems that Russell Brand ended up with some of soon-to-be ex-wife Katy Perry’s clothes after their split. We know the brash Brit comedian likes trendy pieces, but that scarf and those jeans look like they belong in Katy’s closet. (1/4/2012)

Former “High School Musical” hottie Ashley Tisdale has millions in the bank, which means she should be able to afford a sweater dress that isn’t unraveling at the seams. Or at least buy some pants!

Fellow Disney alum Demi Lovato made the mistake of pairing a black lace jacket, dark, dagger-like nails and strappy sandals with an ethereal, off-white dress while signing copies of her Seventeen cover at a SoCal Barnes & Noble on Wednesday night. The hard-meets-soft look totally clashes … and don’t get us started on those ridiculously-tinted hair extensions! (1/4/2012)

We know Rooney Mara was wearing Miu Miu while promoting “The Girl with the Dragon Tattoo” in Berlin, but that “top” just screams, “Hi! I’m a Playtex brassiere from 1950.” (1/5/2012)
