I agree that nude leggings/cycling shorts make me do a double-take, thinking at first the person is naked from the waist down. However, it is just a fashion trend, and mainly worn by the young, slender and toned.
On the other hand, I firmly believe people should wear what they feel comfortable in, and not conform in their clothing choices to please other people.
I'm not a fan of comfortable sandals and sister wife style dresses, but I'd never judge anyone for wearing them, I also don't like the middle-c[ass, middle-aged summer uniform of floral dress, white trainers, cropped denim jacket and accessorised with a crossbody bag - again, if that's what you like, and enjoy wearing, then go ahead. I wouldn't wear either outfit but people who do wear them generally look fabulous, if a little Stepford.
