Hello Deborah,
I agree with the others, you look great. Good luck at your group meeting. I have visited a couple of different groups this year and gained a lot from them. My favorite is in a college town not too far from my home. It is a very diverse group, both age wise as well as cutting across the full rainbow spectrum. I have always felt comfortable and at home. The groups that I go to tend to dress down a bit, I am usually over dressed but have been fully accepted and often complimented. I have usually found what I got out of it was proportional to what I put in. Go for it and enjoy.
Anne
