I am not very good giving outfit advice, but I like your jean skirt idea. I think some wedge moccasins would be cute if you want something other than flip flops. Also, maybe instead of a jean skirt a white skirt would work or a white pair of pants. I love that blazer, by the way. I just wish I could wear ON blazers, but they never fit me right.
Cute jacket--is it seersucker? Here's what I came up with but I think you could do lots of colors. Yellow, lavender, green, etc. Can't wait for spring!
