Kim Kardashian was dressed in black outfits as she celebrated sister Kourtney Kardashian’s wedding to Travis Barker in Portofino, Italy over the weekend.

So it was quite the contrast to see flashback bikini pinup images of her on her Instagram page Tuesday.

These photos of the reality TV maven in a blue bikini were taken several months ago when she first plugged her new swimwear line called SKIMS SWIM.

‘We just announced our Skims Swim launch, which I am so excited about!’ began the sister of Khloe and Kourtney.

‘I’ve wanted swim for a really long time, so I cannot wait for this – I tested all the fabrics myself.’

Kim then said she was happy to have the suits be versatile.

‘The swimsuits are available in seven solid colours and can seamlessly go from day to night, poolside to party, the beach, and more.

On Monday North West – the daughter of Kim and Kanye West shared a revealing TikTok clip from Kourtney and Travis’ splashy Portofino wedding reception held at the medieval Castello Brown fortress.

There were many highlights from the long video with the best being mom Kim dancing to the music with her sister Khloe as they both sang.

Kim seemed to be having the time of her life as she worked up a sweat while grooving to the beat.

The song played over the clip was We Are Family by Sister Sledge, which was a big hit in 1979.

North has not slowed her presence on TikTok even though her father Kanye has made it very clear he feels she is too young to be on the video hosting service.

The clip is full of fun details.

The video was taken by the child, eight, as she walks around the wedding reception which took place on Saturday evening.

Kim was also seen walking in a black D&G gown as she held onto North’s hand.

The Hulu star returned to Los Angeles from Italy on Monday with sister Khloe as she was seen getting off a orivate jet.
