Have you ever tried wearing a muumuu?
Here's what a muumuu looks like.
The muumuu or muʻumuʻu (English pronunciation: /ˈmuːmuː/) is a loose dress of Hawaiian originthat hangs from the shoulder. Muumuu are also popular as maternity wear because they do not restrict the waist.

Although this dress is not in floral prints but its length touches the ground and its loose, so it's still a muumuu. This dress actually best fits large frames.
