Are leggings still in fashion?
It depends who you talk to. The true fashion aficionado would tell you no. Certainly leggings are still in the latest fashion ranges. They're around because they're popular, there's still a lot of customer demand for them.
Obviously leggings work well with tunic tops, but I've also found them useful with short dresses, of which there are lots in fashion. I also use leggings to give a more casual look to an outfit, to dress-it-down, so to speak.
There are some fab patterned leggings around that can be worn with plain tops/dresses/skirts, or mix patterns with patterns. Most leggings are made of cotton-lycra or polyester-elastane. I like 200-denier footless tights, they give a nice finish and are available in a range of colours.
Whatever you do, be careful how you wear leggings and what you wear them with. They're not trousers!
