I am in my 40s, and my leggings are a wardrobe staple. Should I be wearing real trousers instead?
Leggings are a great staple, regardless of age. It's not how old you are; It is all about how you are wearing them.
REMEMBER, at any age LEGGINGS ARE NOT PANTS!
I REPEAT LEGGINGS ARE NOT PANTS!
Leggings should be worn with an oversized button down shirt, a boyfriend blazer, under a jersey or casual type shorter length dress, or with a great sweater. Leggings, for the most part, should be paired with a medium, low or flat heel. Leggings also look great with chic boots.
Keep in mind, there is a very fine line, when wearing leggings with high pumps, between looking chic and of the moment and looking like a girl from a ZZ Top video or Peg Bundy from Married With Children.
