I'm in desperate need of some help. I'm off to Ibiza for the first time in my life and will be heading to a number of the big clubs. What on earth do I wear?! I've heard it's more casual than expected and that the key is to be comfortable. I'm mid 40s and a uk size 16. My usual summer style are maxi or midi dresses but these are more M&S and wouldn't work at all. Any ideas??
