What is a convenient way to ship clothing from Nantes France to the U.S.?

I'm traveling to Nantes to a wedding and will tour Germany and Austria afterwards. We will not need dress clothing for that portion of our trip/

FED EX...and you can check online to see if the dress arrives back home

Whayever their equivalent co.name if to UPS . Box it wrap it well, & mail it . Have fun on the nudist colony!
