スタイルがいい is a beautiful trap for English speakers: in Japanese, スタイル ('style') as a body descriptor doesn't refer to fashion choices — it specifically means physical figure or proportions. A natively wasei-eigo shift in meaning. Saying スタイルがいい about someone is a compliment about their build, not their wardrobe; for fashion you'd want センスがいい ('has good sense') or おしゃれ ('stylish').
