Small hole in the back of the dress (attached an image) Size is 6-12 months but runs big, my daughter is usually true to size and she fit into this at 14 months. A future heirloom, this luxurious merino wool and cashmere blend dress is a wardrobe staple for one generation and the next. Crew neck with buttons at shoulder. Long sleeves.
