When I shop for summer sweaters, I want something that gives me just enough coverage without making me feel overheated. For me, the best lightweight sweater is one I can wear on cool evenings, in air-conditioned places, or during breezy days without feeling bulky or uncomfortable.
What Fabric I Prefer
I always check the fabric first because it makes the biggest difference in summer comfort. My favorite materials are:
- Cotton: soft, breathable, and easy to wear
- Linen blends: airy and great for warmer days

How I Check for Comfort
