Trying one's best not to look at women

Q: Nowadays it is very common to see women in very revealing clothes in public, social media, websites etc. It's difficult for me to be looking away from so many places. Is it okay to let them be in my view if I don't induce sexual thoughts about them? Because I'm used to looking at them by now, but I still feel guilty because it is known to be sinful. Do I have to repent every time I see women wearing obscene outfits?
