姐是你穿不起的牌子货
[jiĕ shì nĭ chuān bù qĭ de pái zi huò]
'I am a brand beyond your reach.' This is often used in a playful or assertive context where 'Sister' (or an older woman) refers to herself as unattainably good or prestigious, usually referring to high-end or branded status, suggesting superiority or self-confidence.
