hi erin,
i moved ths thread to the wedding attire section...if you look at my pics you will see the guys wearing a tan linen suit...we found ours at Jcrew and H&M.
if you look through the attire forum you will find lots of info on tan linen suits.
the one thing to keep in mind...they really start coming out in early spring and there is a really short linen suit season so when you start seeing them you need to grab them quickly.
here's a thread
