Kylie Jenner may have missed the memo, but these three didn't!
All three women opted for pants and pumps at Cosmo's 50th anniversary party in LA on Monday, with Olivia looking gangsta chic in her pinstriped suit and Sarah showing off some tanned skin in pedal pushers and a cropped blazer by DSquared2.
The Modern Family starlet also accessorized with Nicholas Kirkwood heels and Jennifer Fisher jewelry.
Kelly fit right in with both suit-wearing gals in her baggy jumpsuit, though of course her crazy lavender 'do helped set her apart.
It's like Flock of Seagulls meets the ballerina top bun!
