They're the bedrock of our wardrobes, the sartorial failsafes we turn to in times of need and the fashion industry's most democratising item of clothing: Jeans, we owe you big time.

Yes, they might be a sartorial staple that transcends the seasons, but there are certain denim styles that have risen and fallen in popularity, fluctuating as tastes change and demands shift.

With fashion week finally drawing to a close, we thought it would be a good opportunity to look ahead to the jeans styles that are set to spike in 2019. To get a little insider intel, we spoke to Costanza Lombardi, womenswear buyer at luxury fashion store Browns, to discover the three trends she's excited about this year.

So what should we be looking out for? "The first denim trend set to be popular in 2019 has got to be the total denim look, both in classic blue and in tonal colours," Costanza says. "The second is '90s-style jeans. I’ve seen a lot of high-rise, full length, straight-leg pairs with black leather for a real celebration of the decade. Finally, I would say black denim has been very present in a lot of the collections, reflecting this season's celebration of the classic hue."
