Petunia looks very much like her sister Sophronia. They share an oval face, muddy green eyes, a straight nose, a firm mouth, and are of similar height. Petunia's hair is a shade darker than Sophronia's, and her cheeks are rounder.
From very early in the Finishing School series, Petunia (at age 16) already acted like she was fully grown. She cares very much about appearances.

There had been highly intoxicating punch, a variety of dances, good music, and intermission entertainment. No one knew why the beautiful Miss Pelouse had stripped, rolled about in the garden, and then chucked a cheese pie at the youngest Temminnick girl before being taken away in floods of tears, but it was surely the highlight of a most enjoyable evening.” (Etiquette & Espionage, Lesson 17)
