On Friday, the Poosh founder, 44, shared a post on her Instagram Story where she explained what she wore the night before to her husband Travis Barker’s Blink-182 concert at Melbourne, Australia’s Rod Laver Arena.

Kardashian opted for Barker’s oversized white jersey, a black mini skirt, and black knee-high boots, wearing her hair up as she posed for the mirror selfie.

“Last night’s postpartum how to get ready in 5 seconds tip of the day.. wear your husband’s oversized jerseys,” the reality TV star captioned the snap.

The Kardashians star’s latest post comes after she shared some postpartum tips on her Instagram Story on Tuesday, having welcomed son Rocky Thirteen with Barker, 48, on Nov. 1, 2023 at a hospital in Los Angeles.

“Getting dressed postpartum while breastfeeding=throwing on an oversized coat, flat shoes pretty much always, loves leggings, sweats, anything baggy and comfortable aka husband’s vintage t shirts and dickies,” Kardashian, who wore a nude trench coat over a black outfit in the images, wrote.

“And anything super fast to throw on=less time away from my baby the better.. Makeup routine up next,” she added. “2 minute hair & makeup with a baby.”

“Dab @kosas concealer, curl lashes, one coat mascara, brush eyebrows, clear @kyliecosmetics lipgloss,” Kardashian, who has been by Barker’s side throughout his band’s Australian leg of their tour, went on in another post. “Hair wet left to dry however it wants (tuck it in jacket lol).”

The Lemme founder also drew an arrow to a baby mat, telling fans, “a good playmat for baby to play on while you quickly do this routine is everything…or dad’s arms.”

As well as being mom to 3-month-old Rocky, Kardashian also shares son Mason, 14, daughter Penelope, 11, and son Reign, 9, with her ex Scott Disick, 40. Meanwhile, Barker is father to son Landon, 20, daughter Alabama, 18, and stepdaughter Atiana, 24, whom he shares with ex-wife Shanna Moakler. Kardashian and Barker tied the knot in 2022.
