A printed or patterned blazer, as opposed to the more common solid-colored variety, can pose an extra challenge
This is especially true if you’re planning on wearing it to a more formal event or to the workplace. Like any patterned piece, fitting is crucial—wear only the well-fitted blazer you can find.
Pairing-wise, pick light-colored vests to go under the blazer and dark-colored trousers to go with it. Basically, let the blazer be the center of attention.
On a related note, accessories can easily get lost in dense patterns, so think twice about adding brooches, pins or pocket squares.
