There are revivals from such a multitude of eras at the moment, with another being the 50's style Tea Dress. A flattering item for most shapes with it's floaty hemline but team it with a floral print and it's easy to drift from divine to disaster if you don't follow a few simple steps.

 
1. Quality fabric

2. Good tailoring

3. Spend a little more          

 
Obviously it depends on your look, accessories and shape etc but it also depends on the tailoring and material quality. The quality must be high to help you stear clear of the 'granny' look which means spending more money but get this right and you will be onto a winner this Spring.
