What to wear under a cardigan

What goes under a cardigan depends on style and setting. For a professional look, choose a fine-gauge knit top, collared shirt, or silk camisole that complements the cardigan’s color and texture. In casual wear, cotton T-shirts or ribbed tanks create a relaxed aesthetic. The inner layer should be lighter than the cardigan to maintain proportion and airflow. Seamless or flat-knit garments prevent bulk around the torso. In cooler seasons, a merino or cashmere base layer adds warmth without restricting movement. If the cardigan is open-stitch or slightly sheer, select tonal camisoles or long-sleeve undershirts for modest coverage. The key is layering knits that breathe, move, and drape harmoniously.
