When it comes to selecting the right size for a Rick Owens pullover, it is important to pay attention to the sizing chart provided by the brand. Rick Owens generally uses European sizing, so it is recommended to convert your usual size to European sizes for a more accurate fit. Additionally, Rick Owens pullovers are often designed to be oversized, so keep that in mind when selecting your size. If you're unsure about which size to pick, it may be helpful to try on a few different sizes in person or order multiple sizes and return the ones that don't fit properly.
