Dan and I would like our guests to feel comfortable in their attire, and as such are not specifying a strict dress code of the "black tie" variety.  That said, the groomsmen will be wearing tuxedos, and the bridesmaids will be wearing cocktail-style dresses.  We encourage our guests to dress in a semi-formal fashion, which for these purposes will be defined as anything between sportcoat/trousers and a tuxedo for gentlemen, and a cocktail dress or an elegant suit for the ladies.

This note is of particular importance for the men out there, as our reception hall, Sunset Ridge Country Club, has a dress code which they enforce.  A component of the dress code is that men must wear a jacket upon entering the club (either a sport coat or suit of some kind).

I figured I would just throw that out there so you can make preparations if necessary.  If you are in a pinch, Target has jackets for around $60.

Cheers!
