When I mix patterns, (or prints or fabrics or colors) I try to lean towards whimsical, rather than take my outfit (or myself) too seriously. I love to have fun with my clothes/accessories but when taking a “risk”, I find it’s best to be light-hearted.
I really liked the juxtaposition of stripes on the shirt with checkers on the pants but I couldn’t figure out what to do with the shirt because the pants are a little big. I tried tucked in, tied to the side, tied in front and finally settled on tied in the back. Then I rolled the pants.
