Actually, there are those kinds of non judgemental people all over the place. They're called businessmen/women. They don't care about anything at all, just the color of your money, and will gladly help you buy whatever you want, and not think the worse for you no matter what you choose. After you leave their store, they will not consider you a fag or dyke, but they will remember what you like and when you return, will guide you to whatever styles they think you might like.
That said, there are several ebay cosplay merchants out there that will happily help us with custom fitted dresses no matter what our size or shape. Capitalism lives on, no matter what the political nuts want us to believe.
Edit: For those of you who are reluctant to go to buy female style eyeglasses in a store, there are several online eyeglass manufacturers that make VERY reasonably priced specs in any frame you want. I get mine from
www.zennioptical.com; they seem to have thousands of frames, ranging from $7.99 on up, with several hundred for that base price WITH THE PRESCRIPTION LENSES INCLUDED. You need to know your eyeglass prescription and pupillary distance, and that's it. The website conveniently tells you when you pick a frame that won't fit bifocals should your prescription require them. It's real easy to use, and has a flat shipping rate of about $5 no matter how many you buy. It takes anywhere from a few days to a few weeks to get your glasses depending on how busy they are; however, most of mine have come within 7 working days.
