Arrived back from a 10 day holiday on Monday and towards the last few days one of my arms was going really patchy. It looks like some really dodgy fake tan. I caught a great tan, didn't burn at all and was looking forward to wearing nice dresses this summer with a bit of a tan rather than my usual pasty white legs. I always tan well on holiday and this has never happened before. The skin isn't dry and it hasn't peeled. Anyone know what this could by/why it's happened and any tips for disguising it? I tried a bit foundation/bronzer but it just ended up looking muddy and didn't match at all. My legs and other arm aren't like this at all. It actually looks worse in person that it does on the photos.
