Kourtney Kardashian shares her postpartum ‘tip of the day’: shopping in Travis Barker’s closet

She’s borrowing from the boys.

Kourtney Kardashian has been sharing some of her quick and easy postpartum fashion and beauty tips on Instagram lately, and on Friday she posted another new mom hack involving husband Travis Barker’s wardrobe.

The “Kardashians” star, 44 — who gave birth to her fourth child, Rocky, in November — posed in an oversized white jersey in a mirror selfie on her Instagram Story, writing, “last night’s postpartum how to get ready in 5 seconds tip of the day…wear your husband’s oversized jerseys.”

In the pic, she sported a white shirt reading “Speed” on it along with stretchy black bike shorts and tall black boots.

The Poosh founder wore her hair pulled up in a messy updo as she posed in the full-length mirror.

This isn’t the first time she’s worn the easy, oversized style in recent days; she sported a no-pants look at a recent Blink-182 concert while wearing a baggy white football jersey.

Earlier this week, Kardashian shared a series of Stories with other new mom style tips, posing in a trench coat and writing, “Getting dressed postpartum while breastfeeding=throwing on an oversized coat, flat shoes pretty much always.”

In terms of style, she said she “loves leggings, sweats, anything baggy and comfortable aka husband’s vintage t shirts and dickies.”

The reality star — who said she leaves her wet hair to “dry however it wants” — also gave a peek into her beauty faves, sharing that she loves products like Kosas Revealer concealer ($30) and sister Kylie Jenner’s clear Kylie Cosmetics High Gloss Lip Gloss ($18) for a “2 minute hair & makeup with a baby” routine.

Kardashian has certainly had the opportunity to perfect her style tips on the road as she’s accompanied Barker on Blink-182’s tour through Australia and New Zealand in recent weeks.

Whether it’s rocking an oversized trench or a sporty jersey, she’s got new mom style in the bag.
