Suggestions please!

Dear it all depends on what you have in your wardrobe, woulda been easy if i had a slightest clut to what you got but all the same

A simple, yet elegant gown always cuts the not-too-formal-or too-dressed up cake . . or a plain pair of pants with a very flashy topp would also do

Use simple but nice jewelries and accessories to go with the outfit . . and put up a nice hair do, or style if you already have your hair done.

Its not always about the dress, but mostly the person carrying it.

Hope the wedding goes well.
