Oh it is pretty, if only I didn't have big hips and an undefinable waist. Pink would be lovely with it. I'd try it with a fitted vest top for the party and afterwards with a fitted long sleeved button down cardigan.
Ooh that's lovely. <want one> What's the sizing like?
I'd wear it with something plain and fitted e.g. a round-necked, buttoned-up cardi or a fitted T or maybe a cropped sweat shirt. I normally wear colour but with that, I'd probably stick with grey or maybe dark green or plum. Even for a party I'd keep everything else simple and sober and let the skirt do the talking.
