create alias breastless_bra -> cupless_bra
create alias nippleless_bra -> cupless_bra
We have nippleless clothes and breastless clothes, so cupless bra is kinda hard to find. A lot of posts under nippleless clothes and breastless clothes are in fact cupless bras tagged by people (me included) who didn't know about this tag. These utility aliases should help in finding the right tag.
Since bras are made to cover the breasts, bras can't be breastless, so I think they should be implied to nippleless clothes rather than breastless clothes.
