anything really goes in the south of spain due to the heat. It can be 40 degrees everyday but yes the spanish woman do tend to wear dresses but this is usually the older/rich ones.

but demin skirts, linen is alos good and cool. they have great shops but dont expect to get trousers if your over 5ft 6 ish! if your going to the beach in august you would be better of to bring your swinsuit as they are often 45 euro for a plan one. Where do you hope to go. Make sure to also bring a good backpack for hiking up the siera nervida .
