Consonsantia is the second of St. Thomas Aquinas’s requirements for beauty, and it means “proportion” or “harmony”. When applied to dress, consonsantia is primarily reflected in two main fields: in the rule of 2/3rds, and in the wearing of patterns.

Learning how to mix patterns together tastefully, then, isn’t just a question of expanding the possibilities available to you in your wardrobe.
