Lime takes up space

An acid-lime shirt with oversized sleeves meets wide magenta shorts, with violet socks above silver shoes.

Why it works: The two broad shapes give the colours room, while the narrow shoes keep the ankle line precise.
Make it yours · Unexpected colour pairing: Pair a bright loose shirt with wide shorts in a contrasting colour. Let a visible sock add a smaller third note.
