I have been 'crusin' this dress for a while - and I think it has come back in stock!
I love everything about shirt dresses - the way they hang, drape and can have a covered sleeve without looking matronly.
It is a look that those of us over 30 (ahem) can wear with confidence that we are not doing the mutton lamb lamby-lamby thing - which I try so hard to avoid, but makes me sad when I see 'pretty' things. Not skanky things, pretty things. Death to the bodycon dress!
Plain shift dresses are also great for the office, a standby 'wedding guest' dress, and can be dressed down with sandals & a straw bag for a bbq, or dressed up with a unusual necklace and some outrageous heels for something more chic - and hair up girls!
