STYLETHREAD -- LET'S TALK SHOP!

One of my good friends is having a bridal shower this month. It's quite swanky; it's actually a "bridal high tea" at the Ritz-Carlton. For reference, it's the same day as her bachelorette party, and the theme for the whole thing is "Summer in the Hamptons." I am wearing dressy berdmudas to the bachelorette, I think. Anyway, I want to wear this dress, borrowed from my sister. (Forgive the bad pic, I only have a cameraphone at the moment.)

 detail of the dress:

I think it needs a little jacket or a cardigan, and maybe a belt or ribbon. Any ideas? The color is sort of a bright green/chartreuse. I can borrow a cute brown and white wicker clutch to wear with it.   These are some shoe possibilities. Of course, I could always buy more shoes.

white wedges, burgundy peep-toes, brown stacked-heel sandals and brown slingback sandals.

Any suggestions? TIA
