Summer Lust Have: The Dip Back Skirt / Dress

I am lusting after the dip back/scoop back skirt or dress at the moment.

Given my penchant for polka dots, I am devastated that I missed out on this super discounted (reduced to 12 pounds) dip back dress from Dorothy Perkins (all totally sold out, and has been for weeks – I keep checking and it doesn’t look like there’ll be any stock added):

I also love the look of this ‘Waterfall’ skirt from Glassons, but I think I need to try it on before committing:

What is your lust have for summer, and have you seen any other dip back skirts or dresses that you can direct me to?
