My original plan was to make either a round headdress or some bows to wear on pigtails from the same lace as the sock toppers, with green ribbons on them. But I can't find any ribbon that's close enough in colour, or of a similar type (ie as nice quality) as the stuff on the dress, so I'm concerned that might look a little wrong.
So I was thinking maybe a hat might look nice, although I'm not sure what style. I've already got a beret (well, ordered, not got it yet), but it's grey, not white. What do you all think would co-ordinate well with the dress? For reference the full outfit so far is white lace-topped socks, black mary janes, a white Baby parasol, and a bag to match the dress.
