Gigi Hadid displays her pert posterior in skintight white trousers before sharing a laugh with her grandmother at Berlin fashion event 

She's one of the world's top supermodels and Gigi Hadid showed exactly why at the Bread & Butter by Zalando event in Berlin on Friday. 

The 21-year-old star showed off her incredible figure in a pair of skintight white trousers and a fitted black bodysuit which plunged low in the back. 

And although Gigi was hard at work promoting her Tommy x Gigi collaboration with Tommy Hilfiger at the event, she made time to share a laugh with her grandmother, who accompanied her to the event.

* PRICES MAY NOT BE AS ADVERTISED

While Gigi is clearly excited about her new fashion range, many of her fans have been left disappointed by the price. 

Among the most expensive pieces are a £575 pair of leather trousers, a £410 wool pea coat and a £290 printed maxi dress.

The nautical-themed collection consists of flared jeans, chunky knits and even a sports bra and shorts set, in a colour palette sticking mainly to navy, cream and grey.

However, those wanting to snap up a bargain will be relieved to know prices start at £15 for 'boot cuffs' (ankle warmers) and cotton briefs - and The Girl eau de toilette is equally affordable at £25.

But as the online shop launched this week, some fans flocked to social media to complain about the prices.

One Instagrammer, known as Anna, wrote: 'I wanted the collection so bad. Now I have enough money for one sweatshirt.'

Another fan added: 'I love them all but I'll never be able to afford any of this,' while Maria, from Stockholm, balked at the $300 (around £250) price tag on one of the garments.
