Respectable B

There are two styles of champagne glasses: one is a flute which features a deep, narrow mouthed bowl which helps to retain the bubbles.

And the second: a saucer with a wide, shallow bowl.

The latter supposedly modeled from the bosom of Mme. de Pompadour, mistress of Louis XV.

To those Americans who prefer basketball-sized silicone, I would personally rather liken a perfectly good B cup to a crystal champagne glass...

For more (and always good) info see Emily Evans Eerdmans post.

and for more on the quiet, shy but very active Louis XV see here...
