The patterns
The pattern is in the fabric, not printed on it. Houndstooth, glen plaid, tweed, stripes and checks: they are woven, which explains why they do not lose their shape when worn or fade in the wash.
This season, the leopard print is on a camel and brown background—more muted than the beige of five years ago, and much easier to wear.
A rule that applies to everyone: only one patterned piece per outfit, the rest solid.
