Weddingbee boards

I bought a couple of bridesmaids dresses from Macy's because they were ridiculously cheap and fit my sister's (MOH) requests that her dress a) have sleeves and b) be brown.  She tried it on today and said that she thinks it's nice but she's going to have to jazz it up because it is plain.  So can y'all help me come up with accessory ideas?  My color palette is espresso, light brown, sage, and white.  (The venue is brown and light brown, and I want to decorate the place mostly white with a bit of green).  The bouquets will be white/ivory with a few green accents, and I would love for the accessories to be white *if* it looks nice. Ivory would be okay too since I think I want an ivory wedding dress.  Please help me, I have no fashion sense whatsoever!

We're on a budget so the cheaper, the better!  Definitely no more than $50 per person.
