Would Koreans be mad about this?

Hello Reddit boys. So today I started doing my budgeting for the year. As such, I’ve pretty much planned out certain expenses. Two of which are Pride and NYE. So for Pride I have a pretty cute idea but it involves me wearing a gat. I’m not necessarily wearing it as a costume. It would just look great with the outfit I’ve got in mind! But I don’t want to wear it if it would be perceived as offensive.
