As United Airlines bars passengers wearing leggings, let's note the dos and don'ts for wearing this controversial clothing item

United Airlines made headlines for all the wrong reasons over the weekend, after they barred two girls from boarding a plane because they were wearing leggings.

Twitter users accused the company of "policing" women's clothing and, as such, a discussion has kicked off about the right and wrong ways to wear this clearly divisive item of clothing.

The sartorial issues to navigate when wearing leggings seem to be the 'spray on' effect (an often unflattering look that can be even trickier to pull off if the fabric is thin and goes see-through) plus the trousers' association with sportswear, which, for United, made them too casual to comply with their dress code.

We have Los Angeles to thank for the fact it is now deemed socially acceptable to wear leggings outside the gym. Our glossy neighbours across the pond think nothing of hitting an early spin class and then heading straight to a morning meeting (via a green juice bar, natch). Later they might meet friends at a bar, still wearing the same leg-hugging lycra.

If you thought the gym wear as daywear trend only applied to this Soulcycle set, and Kendall and Gigi’s glossy model posse, you were wrong. A growing number of UK women are realising the potential of lycra outside the gym.

Women are increasingly time poor so being able to transition activewear into a daytime look is important for our customers lifestyle, whether running to an informal meeting or catching up with friends for coffee," ‎explains Matches Fashion buying director Natalie Kingham.

Women are not just wearing the tired joggers they have had for years, but actively buying into ‘athleisure’, as they would any other fashion trend. Net-a-Porter retail fashion director Lisa Aiken reports that the e-tailer has seen a rise in popularity of leggings over past seasons, and thus the team has increased the buy of activewear brands such as Live The Process, The Upside, Nike and Adidas by Stella McCartney. Matches, meanwhile, continues to up its stock of contemporary brands, such as Laain and LNDR, that embrace athleticism in their collections.
