For my BiL’s 60th birthday, which is coming up, I want to give my sister an alluring sartorial gift with a note that says something like “he’s old, not dead” with a wink. There is precedent for this; they said they enjoyed similar gifts I’ve gotten them in the past, and he once asked me to help him find something similar for her, so I think they’ll like it. I’ve got some time to think about it, which is good, because I need to figure out what to get.
I know he likes the look of otk socks, so I want to build her outfit around that. It should be more daring than http://www.rocknsocks.com but *not* as far as a sexy schoolgirl or dominetrix in black or harsh red, which seem to be the two main looks, along with a host of costumes—Dorothy! The wicked witch! A nurse! A teacher! (Really just a variation on dominitrix)—that come up when I try to google fun outfit ideas with otk socks. Can you help me brainstorm appealing outfits for her to wear in a very private setting?
