After a fall season awash in tartans, the preference for plaids shows no signs of slowing down. For warmer weather there are crisp plaids for lightweights coats, tailored pants or easy dresses. Plaids are used head-to-toe in matched sets or jumpsuits, or as separates ensembled with florals or other plaids. Yarn-dyed checks look especially fresh for pattern-blocking, as in a twisted dress with contrasting plaid panels. The big plaid shirt is still a statement piece, worn on its own or tied around the waist for a post-grunge layer.
