Take a look at this, for example. There isn't a woman alive who wouldn't feel instantly prettier, more feminine, I dare say more capable in the kitchen wearing this darling apron -- even if she is just transferring fish sticks from the baking sheet to the Elmo plate. It's $28, by the way. You can't tell me your girlfriend isn't worth that.
Throw in these pretty measuring spoons if you really like her. So much nicer than the Plain Jane ones I use from the hardware store.
