Of course, Hanfu can be made at will, because it is just a piece of clothing without a registered trademark, so no matter how you wear it or do it, it is not illegal.
But here I kindly remind that different styles of Hanfu are different. If you don't mind other people's eyes at all, you can make your own suit and wear it out to play.
However, if you are still worried about the harassment of some Hanfu policemen, then I still suggest that you do a good job, not to mention how exquisite it is, at least to ensure that the minimum styles are the same, such as not wearing Amin Hanfu, and keeping A Qing Dynasty hairstyle.
If you don't know much about this piece, you can consider taking some photos in Hanfu store and taking them back to do it yourself.

This is a national chain store of ancient Chinese clothing. I say this because this store has 1500 pieces of original clothes from China. I believe I can choose the one that suits you best.
Hope to adopt, thank you.
