So this is one of the outfits I chose whilst as Miss Selfridge's festival fever event! I think this two piece is just as fabulous as a jumpsuit, however it would definitely be more of your friend in a porta-loo situation! It's comfy, but colourful and is quite universal weather wise- easily layered up or layered down. I've paired it with one of Miss Selfridge's 'coatigans' just as an example of how to layer up. This jacket I LOVE though, such a nice fit and shape for spring/summer. Also from Miss Selfridge is this head piece just to complete the festival look! 

You could pair with wellies/boots, but in this situation I'm just wearing sandals. Likewise a bumbag would suffice but I have my Grafea!
