Should I listen to him?

Lately my boyfriend has been making comments about how I dress when I go out, jokingly saying that I dress like a 'single girl trying to get laid' and that I look almost naked in what I wear. I dont feel like I dress too revealing in comparison to most girls my age (21), I usually just wear mini skirts with lowish cut tops. Usually his comments dont bother me but lately I have started to worry that maybe hes right and maybe I should be a bit more conservative in how I dress, especially considering I do tend to attract the wrong kind of attention as my boobs are slightly on the bigger side and arent usually hidden. I also need to say that he isnt trying to be mean or harsh in what he says, but I can tell he wishes I covered up a bit more. What do you girls think? Should I start dressing more conservatively or just wear what I usually do?
