NWR: Free photo shoot!

In my area we have tons of Buy/Sell/Trade groups on facebook. Recently there was a post on one stating that this gal was just starting her photography business and that she was looking for people to take photos of. She was willing to give them a free 1.5 hour session and give them a disc of photos with copyright release. DH and I told her we were interested and she called me last night saying she wanted us to be one of the groups she takes photos of!! We have decided we are taking them with our dogs. Some with all 3 of our dogs and then some of just our border collies with us, that way we can start a facebook page to promote our borders as we plan on breeding. Any suggestions on outfits? (For me) Dh will be in his blue jeans, black felt hat, and a nice western shirt.
