For a more playful and whimsical look, opt for a tulle skirt and sweater combo. The tulle skirt adds a touch of femininity and fun, while the cozy sweater keeps you warm and comfortable. The skirt can be in a festive color like red or green, or you can go for a classic black or white. Pair it with some ankle boots or ballet flats for a cute and stylish outfit that's perfect for a casual Christmas gathering.
