How to wear my cross

So i recently made a post asking if i should wear the cross on the inside or keep it in my shirt and most people said wear it out but i want to know how to wear it without showing off or making it look like a fashion choice. It is a decent sized cross because i 3d printed it and if i did the small flat cross it would break when i take it off the plate. So if anyone can help me figure out how to wear it without looking like i am showing off or anything like that.
