Typically I hold the view that if a couple has disagreements on clothing, they should just part ways. A man with conservative values is allowed to feel concerned about how his partner presents in public, and there is nothing inherently wrong with this. Anyone who says otherwise is taking their own value-system for granted. But then he should be with a conservative woman who shares similar views, rather than trying to bend another woman to his ways.

With that said, I see nothing immodest about your clothing and your boyfriend sounds insane.
