I agree, dress appropriately for the venue and confidence are the only requirements! Scout out the GGs at the venue and then dress appropriately! Take a big gulp of air and say here we go and step forward! You are now off on an adventure! Just do it and enjoy! Most people do not notice and the ones that do may give you a second glance but mostly are caught up in their own business! Just my $0.02! Hugs and best wishes! Lana Mae
