I like this color combo (sea green over navy blue) over dark denim, sweater needs the heathered knit, not solid if wearing a non traditional color. J Crew style, sea green cotton sweatshirt worn over blue checked shirt with denim.
Like this look with denim shirt, Barrow Bologna chinos, IWC watch mod. Portuguese and knitted tie. I usually like aknitted tie with with a denim shirt. But not with chinos/khakis. I'd rather had this look without the tie
