From http://www.christinehaynes.com/:
"The Chelsea Dress is a sweet and modern baby doll dress. Both versions pull on and feature raglan sleeves and dress that gather into the upper yoke.
View A has a contrast yoke, Peter Pan collar with a 3-button closure, short sleeves, and hits above the knee.
View B has a V-neck collar with bias cut bow, 3/4 length sleeves, and band at the hem that hits at the knee."
