Going on a sun holiday next month and I really love the bronzed look! I'm wondering if I should get a spray tan beforehand or is there no point? I won't be swimming as such but having a quick dip every so often to cool off (hopefully!) I don't want it to be all patchy within a day or so but would really like to not be pasty white. Are there brands that hold up better or would it just be a waste of time & money?
