Partner is planning on ballet flats

Hard to say without more context really.
What does your partner normally wear?

View quoted message Oh ok my partner tends to wear your normal mens clothes really and has never even shown interest in womens fashion Before and whenever he's worn a suit he's always just worn mens loafers with them

View quoted message Oh right okay in that case are you 100% sure he is being serious? That’s the sort of thing my fiancé would try to wind me up about. Or does he definitely understand what Ballet Flats are because I agree with you it’s a bit strange

View quoted message Yeah knowing my partner like I do he is being 100% serious and yeah today when we were putting shoes on to go out he passed me my ballet flats and said "here are your ballet flats love" so he knows what they are and yeah I find it strange as well

You need to ask him, not us.

This is obviously something that has taken you by surprise and that you feel uncomfortable with, or you wouldn't be posting here. But we can't answer your questions. So have the conversation. You need to be able to communicate openly with the person you are planning to marry, especially about anything that is concerning you.
