Do yourself a favor. Don’t be fooled by any signs that the weather is currently warming. We’re in False Spring, also known as Fool’s Spring. It’s still Winter and, at any moment, the weather could shift back to frigid.
It’s still time for sweaters. You’ll likely regret it if you start packing them up for storage now. You’re going to want to wear them for a while yet.
At the very least, if you’re hellbent on forgoing sweater, at least wear some thigh-high socks to keep your legs warm.
