'tough beauty'Duffy begins this stanza with a oxymoron, 'tough beauty' displaying how a woman is both beautiful and powerful. Using her beauty to gain leverage and being able to outsmart the men in her way - she is equal with Caesar 'matched him glass for glass' implying that though feminine, she holds equal power to him. 'Tough beauty' also contrasts 'dumb beauty' and 'beauty is fame' suggesting that beauty standards are constantly evolving.
