Dianne of Dianne in the Provinces fame, passed on “one of the neatest things” she has found: a website for buying eyeglasses online called Firmoo.com. You upload your picture and it lets you "virtually" try on glasses!
Dianne broke her gender neutral spare glasses on a trip and decided it was time for something non-neutral. She picked out a pair that compliments her hair and style and they were a whopping $40!
I know there are other eyeglass websites that do the virtual try-on and have attractive prices (just Google "eyeglasses" and shop around). But since I have no firsthand experience with them, I cannot recommend one, but Dianne seems happy with Firmoo.com, so there you go.
My own eyeglasses are gender neutral, but I have been thinking about getting girly glasses for girl time and going the online route to get them. I will definitely check out Firmoo.com when I do.
