Patagonia Capilene Midweight Set Top: 12-18 months Bottoms: 2T The bottoms are quite slim, so the sizes are different, but I used to dress them as a set around the same time. Both top and bottom have been worn about 5 times. *There is a small, inconspicuous stain on the lower left of the top, but otherwise there are no stains. For those who don't mind. Thank you for looking.
