Bring on the cold! She'll stay warm in this outfit with thick 100% organic cotton poorboy up top (Grandma always said to keep those chests warm!) The skirt is gathered nice and full for twirling, 100% organic cotton. Our black leggings have just a touch of Lycra for great stretch and recovery (93% organic cotton, 7% lycra.) Girls size 6 only for the set and sizes 7 & 8 for the dress only.
