OOTD: Heatwave workwear

Now I love sunshine and I love hot weather but not when I'm stuck in a office with the weakest air con that may as well just be switched off completely. Also I have no pool to dive into or at least sit on the edge/stairs with my book and a strawberry daiquiri or a peach Bellini (or possibly both, like I would do that!?!) within a fingers reach. I NEED MY HOLIDAY! 

So back onto the main reason for this post, the dress. Brought in Miss Selfridge (Oxford Street) in the sale for £10, Bargain! Known as their Floral Lace Slip Dress, it's floral patterned with delicate lace detail about the neck line and hem. It also has adjustable straps which I find really handy having quite a petite frame. Now I've checked online and I can no longer see it but if you go to a big store they may still have as I only brought 2 weeks ago. However, I brought from their petite range so I'm unsure whether it's sold in the regular (I can't imagine it wouldn't be) 

How are you surviving this British Heatwave?
