If this isn't the ultimate Boho Summer dress I don't know what is! 
Cute, floral and on or off the shoulder. 
Stretchy waist and crimped across the chest, tie detail at top of the back. 
 
Size reference; first photo I'm wearing a Large and I'm usually a UK12. The other two photos of our model Rhona is wearing a small and she is usually a UK8.
