Love the strappy tie-back on this sundress - I first thought it was denim.....then suede...but I am not sure it is either! In any event, a gorgeous summery dress for hot weather. Edit: It is a suede Theory dress!
A simple, beautiful way to dress up a simple slip dress - add a print neck scarf. A rich jewel-coloured slip dress (or even a lovely print - Topshop have a gorgeous palm print slip here) would work beautifully with a scarf for the middle of summer.
