That's a famous brand, isn't it.
Literal
Famous-[attributive-な] brand is-[polite-ですね].
Terse but complete observation — subject omitted, context supplies what's being discussed. ですね combines the polite copula です with the agreement-seeking ね. ブランド ('brand') is a katakana loanword central to modern shopping and fashion talk. Short and natural.
