This one [[http://www.johnlewis.com/312460/Product.aspx here]] - silk and colourful. Or this one [[http://www.zara.com/webapp/wcs/stores/servlet/product/uk/en/zara-W2011-r/164011/632731/PRINTED%2BDRESS here]]. More muted, with good sleeves but man made fibres? To be worn with leggings and flats probably.
