"Regardless of what you might have heard...." "I am going to wear this outfit regardless of what my mother thinks." "It doesn't matter, regardless." "Regardless of my diet, I am going to eat some cake."
those are all i could think of off the top of my head, sorry. :/
Thank you. I have another question. Is there a major difference between "regardless of" and "no matter"? For example, can I say: "No matter what you might have heard...." "I am going to wear this outfit no matter what my mother thinks."
