Robert Pattinson is opening up about his style — and getting real about his favorite and least favorite looks.

The 33-year old actor spoke to British GQ about a number of topics including his work as the face of Dior Homme and his appreciation for self-care. However, on the topic of his fashion choices, the Twilight actor had one major regret: his Harry Potter and the Goblet of Fire premiere outfit in 2005.
