[6] Yoga pants took some years to spread around the world; the first Lululemon store in Europe opened in 2014, in London, England's Covent Garden.

[11] Basic yoga pants are black, tight-fitted, boot-cut, flared, and reversible; they are made of a four-way stretch fabric, with a flat elastic waistband at the top.

They may be made from blends of cotton, Lycra spandex, nylon, polyester, wool, or similar light and stretchy synthetic material giving the pants a soft, smooth finish.

[19] Suzanne Wexler, writing in the Vancouver Sun, agreed, calling yoga pants with heels and blouse "a fashion faux pas".

[8] Rachel Marlow, writing in Vogue, said that yoga pants had become acceptable wear for women "on the school run, in the line for morning coffee, over a business lunch, or even drinks".

[26] Hollie Shaw, writing in the Financial Post in 2015, talked about the "Lululemon effect"[28] which had replaced jeans with yoga pants and observed that men too were starting to wear them instead of denim.

[29] In Montana, a 2015 bill supposedly sought to outlaw both yoga pants and leggings,[33] but the representative concerned, David Moore, claimed that this had been a joke.

"[35] Time magazine recorded that in 2016, a man in Rhode Island wrote to a local newspaper calling the wearing of yoga pants by women "bizarre and disturbing"; in response, hundreds of demonstrators in tight clothing assembled in front of his house.

[37] Anne Kingston disagreed with Jones, writing in Maclean's in 2018 that a looser style of sweatpants had already re-entered athleisure fashion, and that there were solid practical reasons for tight yoga pants, such as that they make it easier for instructors and students to check their body alignment, reducing the risk of injury.
