You're never to old for this one!
I have the long sleeved version of this dress in cord and also the black seersucker type fabric. It is beautiful on, although my work colleague did say the green cord was a bit 'Maid Marian' due to the billowy sleeves I'm a 10/12 and bought it in the 12 - the 10 was a bit snug under the bust. I wear a camisole underneath as it its very low cut.
Next also sell Nobody's Child online if that helps?
