Tigeratty, I just recently had to purchase my first pair of glasses. I knew that these would be an investment I would have for a long time, so I went to a local specialty store, too. I would recommend finding one in your area.
The one I went to was great. The ladies who helped me were absolutely stylish and gave me great feedback (it wasn't just--oh those look so good on you). Plus, once I narrowed the selection down to 4, they have this handy-dandy machine that takes your photos with each pair and then puts them altogether on a screen so you can see what they all look like side-by-side. That was a great way to decide.
This particular store had several brands, but the ones I was most impressed with because of their funkiness were OG (oliver goldsmith) http://www.olivergoldsmith.co.uk/
and Lafont: http://www.lafont-paris.com/Home.aspx
I ended up purchasing a pair of Lafont.
I am an attorney, too, but on most days I can get by with funky, smart casual. I needed a pair of glasses that would look just as good with my funky downtime clothes as with a suit. I don't think you need to get something just conservative; buy something with enough funk that you feel stylish in them. The suit will "dress down" the glasses.
Good Luck!
