What to Wear to a Shoes Optional Wedding
Common for beach and backyard weddings, this invites guests to go barefoot. This doesn't mean casual, only that shoes are not required. If you don't feel comfortable going barefoot, wear your favorite summer shoes -- just avoid heels, which will likely sink into a lawn or beach.
Dress pants with a button-down or polo shirt.
A pretty sundress or skirt -- and don't forget a pedicure!
