I plan to put mine on the lower front part of a vest, possibly off to the sides a little. I for one can't put it on my pants anywhere near the waist/hip because I will have a bustle that would otherwise cover it up.
For the other version (possibly first since it's easier) I'll probably just be getting a necklace version I saw on Etsy. Unless I use the same pants then I might put it somewhere on those and not worry about it being hidden when I get my nicer one. Decisions, decisions...
