just a few tried and tested ideas
if you have a clit ring you could put a padlock on it the pleasure soon turns into an 'uncomfortable' reminder and can make you feel very concious especially when wearing a short skirt and no knickers.

maybe a bra with a couple of pintacks pierced through the material ..be careful how you move or bend over lol

or sellotaping your nipples down wearing a light see through blouse.

or a bit of rope bondage in your hair attached to your collar if you're wearing one or a sturdy enough choker of some description..can be done if your hairs long enough,not loose but not too tight either or you'll end up scalping yourself lol it looks good feels good and people do notice it.

a bit of rope round your toes coming up slightly above your ankles, with some light strappy shoes/sandals ..takes a lot of practice but worth it,

(on the boring side..make sure wherever you are especially if alone that anything you do is easily removable when necassary,even light forms of bondage can after a while affect your circulation.)
