Navy tuxedo jacket with satin lapels

I found a navy tuxedo jacket with black satin lapels, plus matching trousers, in a garment bag this afternoon around 3pm behind the East Side Plaza on Main Street in Sterling, CO. The jacket is a size 40R, likely Calvin Klein, with a small copper lapel pin in the shape of a bow and a faint crease from being tucked into the bag. Inside pocket there's a lavender handkerchief with initials 'DP' embroidered—definitely a personal touch. It seems someone was getting ready for a formal event, and I know how stressful losing something like this can; I’d really like to help the owner get it back.
