tyr the main sity they have some lovely shops there and if it si shops like Mango, Zara, Stradvarious, they also have a Carte De Ingles Department store where they do Baby Phat clothes, all the labels that your 16 year old might like and wil defo heard of and theya re a fraction of the cost here
I went mad in carte De Ingles and Mango as the prices were ridiculous compared to waht we pay here in the UK, for the desiganer label clothes, but this was in the capital of tenerife which was quite a bus ride away from PLA.
Hope you haev agreat holiday and your daughter enjoys herself
