Sorry this is such a stupid question! I don't really look at the temperature numbers at home in the U.K. I just get dressed according to the weather.
I'm going on holiday to the south of France and the weather says it will be 23-25 degrees. I don't know what kind of clothes that means. The last time I went on holiday was ages ago and I misjudged the weather forecast, was far too hot and ended up having to buy some shorts!
I'd be very grateful to have any suggestions!
