OK, I searched similar questions on https://english.stackexchange.com/ and it seems that people say that
to love to do something=prefer to do something
to love doing something=enjoy doing something
OK, see conversation 1:
Tom: I'm going to wear my casual t-shirt to the party
Jack: On the contrary, I love to dress up
Now conversation 2:
Tom: I like my casual t-shirt very much
Jack: On the contrary, I love dressing up
So, am I understanding it correctly?
If not, when do you use “to love to do something” and “to love doing something*”?
