Kylie and Kendall Jenner have been working on a joint fashion line for years.

And on Monday the duo were back at promoting their line as they shared another look from their spring campaign on Instagram where they were posed together.

In the caption, the power sisters even credited the man who did the retouching for the pH๏τograph in a rare move.

The caption began, ‘Thanks to everyone that helped with our spring shoot, we couldn’t have done it without you,’

They also said there was ‘more to come soon.’

Next the duo credited the pH๏τographer, Sasha Samsonova as well as others in their team like Mary Phillips, Jesus for hair.

And then a name came up that seemed unusual: ‘@retouch_by_yul_zh.’

Yul Zh is a post-production artist who has worked with Kylie before, like on her Playboy cover.

He has also worked with Kylie on some of her makeup shoots with Sasha. And he has done touch up work on shoots with Jessica Alba, Laura Dern and Ciara.

Kendall was in a print dress with Cult Gaia earrings while Kylie was in an off the shoulder dress.

Last week Kendall was seen in an image from the line.

Long before she self-isolated due to the coronavirus pandemic, the 24-year-old Keeping Up With The Kardashians star posed in a white ʙικιɴι, showing off her enviable supermodel figure.

The suit was co-designed with her younger sister Kylie Jenner for their holiday 2019 Kendall + Kylie line.

The ex of Ben Simmons also had on a stylish hat as she posed outdoors.

The caption read: ‘A little something for your Wednesday Holiday 2019 sH๏τ by @sashasamsonova and styled by @danixmichelle in an incredible @gladystamezmillinery oversized Panama Straw Hat.’

The retouch expert was not credited here.

The siren had her makeup perfectly done with neutral tones as the hat took over the shoot.

It’s been a crazy time for Kendall as she was seen in the middle of a physical fight between Kourtney and Kim on KUWTK.

Kendall was told she was sick so she did not do the work she was supposed to. Kim added that she had to step in.

The Vogue cover girl seemed annoyed but blew it off.

However, when Kim told Kourtney she does not do the work because she does not care, the 40-year-old mother-of-threw blew up.

Kim said Kourtney scratched her so hard she drew blood.

Also in March Kendall was seen in both a Calvin Klein shoot, where she showed off her killer curves, and a SKIMS shoot to mark the 6 month anniversary of Kim’s brand.

Last month, Kylie shared with her Instagram followers that she got used to staying home all the time while pregnant with Stormi.

‘I’m on day 8. My pregnancy prepared me for this, I didn’t leave the house for months,’ she said last Wednesday.

After falling pregnant by rapper Travis Scott in 2017, Kylie took extensive measures to conceal her growing baby bump.

She hid it with baggy clothing in Instagram snaps and kept out of the public eye as much as possible throughout the end of 2017 and the start of 2018.

The beauty only confirmed her pregnancy when she announced the news that she had given birth to a baby girl on February 1, 2018.
