Wool cardigans are a staple in cottagecore fashion, adding a cozy and rustic touch to any outfit. Pairing a wool cardigan with a flowy floral dress and a pair of lace-up boots creates a whimsical and romantic look perfect for a day in the countryside. For a more casual vibe, layer the cardigan over a ruffled blouse and high-waisted jeans, completing the outfit with a pair of vintage-inspired loafers. The versatility of a wool cardigan makes it a versatile piece that can easily be dressed up or down to suit any cottagecore aesthetic.
