"More skin", "Modesty", "Less curves" .. these are all ambiguous terms. Really. What does "more skin" mean to somebody from UAE, India, USA and a nude beach? Let me elaborate. Someone from the UAE would think a woman without her burqa is immodest and must be stoned. To some cultures in India, a woman wearing a sleeveless shirt is immodest and is ill-cultured. To a person from the USA, it is a bikini suit. To a nudist, well, wearing something might be immodest.
I think it is time we stop advising the opposite gender dress modestly, show less skin and curves. We do not have a universally applicable set of codes for dressing. And please do not use the Bible as a shield for your argument. There are various passages in the Bible (both, OT & NT) that exhort women to lay off ornaments, not plait their hair, not worship with uncovered heads, etc. And the percentage of women who follow this is only a few. The same goes for men as well.
So, my suggestion is that if you have a problem with someone's dressing, then the problem is with you. If you look through a yellow lens then the whole world will appear yellow to you. Blaming women for your sin is like blaming the world for appearing yellow to you. Trying to advise the opposite gender to dress modestly/show less curves/etc. is only trying to shift the responsibility for your behaviour on them. This is the basis for arguments that many men use to justify incidents of rape - that women who dress immodestly are only asking for it. I am sorry but if you have a problem with a person's dressing, then you are solely responsible for it.
We have progressed a lot as a civilization. Let us not reverse this progress.
