This Is Not Just Sexism, This Is M&S Sexism?
Big or small. We like them all. At M&S you'll find beautiful bras to fit all sizes, at gorgeous prices. If nature has blessed you with more than your fair share, you certainly won't be charged extra for it. That big boob is all in the past. Bra £18. Knickers £8.
If you're going for "clever" it's better to be really knowing and consider what an impersonal body and double-entendres actually say to a customer who's also been exposed to ideas such as the campaign for real beauty and whom you're hoping to make feel good about themselves. Or perhaps I'm wrong and it's all good fun.
