How about having a look at dorothy perkins? they do such a wide variety of tunic/dresses that can be dressed up. I love tunics as the skim over my spare tyres of flab bumps. If you get A line shaped ones they look really structured and smart failing that maxi dresses are right bang on trend and personally i think they look soo feminine whilst not being clingy whatsoever
this is very pretty on with dark tights I normally would wear a broader belt however the skinny belt that comes with it is nice It is much longer on me I'm a 14 in most shops, but the 12 in this is fine one me.
