A not-so-guilty-pleasure for me: geeky cufflinks.
The man wearing them could still look dapper in his tux, but there's a sweet secret on his wrists: cufflinks that reveal more about him than a black and white suit. These Camera Cufflinks ($68), in particular, are for the photography aficionado, professional or amateur.
Geeky, cute, but, are they appropriate for a formal occasion? I think they are, but I'd love to hear what you think!
