This season is all about the red leg. Fashion bloggers first started wearing red tights during the winter months. Now that spring is coming to the northern hemisphere, they're switching to red pants. The trend works for all ages, shapes and budgets. Fast-fashion companies including H&M, Zara and Topshop have inexpensive versions either online or in-store, including cropped styles suitable for summer. A search for "red pants" on Yoox.com turns up options ranging from $50 to $1,000. Here's a look at the fashion bloggers who have been caught red-legged lately.
