Kylie Jenner is basically a walking fashion statement at all times, and it looks like Modern Family star Ariel Winter is following in her heeled footsteps. The two 18-year-olds — yes, they're only 18!! — aren't afraid to show off their style in plunging necklines and daring cutouts.

Most recently, Winter rocked a sleek pale pink dress that was all about the underboob at her high school graduation party.

"I couldn't be luckier or more grateful," she captioned the pic below. Her commencement was last Monday, June 13, and she's heading to UCLA, where she's interested in studying law.

Kylie's also been working the peekaboo look lately. She wore this House of CB jumpsuit for a night out earlier this month. Clearly, underboob is the new sideboob.

Here are few more times these fashionistas twinned, starting with these jaw-dropping blue lace gowns.

You can never go wrong with all black, all the time.

White pantsuits are pretty cool, too.

Crop tops are a must.

Short shorts are a summer essential.

And, finally, don't let anyone ever tell you hoodies aren't fashionable. These sweats belong on the runway.
