How to match trousers with sailor suit

Pairing navy-style sailor suits with pants:

1. Pants that match the top; this gives a sense of integrity and is very coordinated.

2. Denim shorts, which can turn a serious outfit into a lively one, making it more elegant.

3. Pants that have slimmer legs. The color should not be very bright, nor should it give people a top-heavy feeling, so as to show the individual's slenderness and elegance.
