And just so you know... http://en.wikipedia.org/wiki/Muumuu
The muumuu or muʻumuʻu (English pronunciation: /ˈmuːmuː/) is a loose dress of Hawaiian origin that hangs from the shoulder. Like the Aloha shirt, muumuu exports are often brilliantly colored with floral patterns of generic Polynesian motifs. Muumuu for local Hawaiian residents are more subdued in tone. Muumuu are no longer as widely worn at work as the aloha shirt, but continue to be the preferred formal dress for weddings and festivals such as the Merrie Monarch hula competition.
The pattern and instructions are still factory folded. The envelope shows just a little wear and creases from storage.
