For all you hardcore drinkers of the female persuasion, I present the Winerack from thebeerbelly.com. This is a bra that holds liquid to boost your breast size and to hide your pre-noon buzz-sauce. I don't advise you wearing this on first dates.
Implications - Items such as this beer-filled bra are are good for jokesters who want to prank their friends. Pranks are fun for most people and items that can help them pull off a great one are going to be scooped up by devious consumers. April Fools day is a great time of year to sell a product like this (and it can conveniently store your beer too!).
