Where to find UV protection swimwear?

Does anyone know where I can buy adult-size UV protection swimwear like this in Santo Domingo?

I've seen it in kids' sizes in Prin and Price Smart but I want to buy an adult-size top when I go out later today.

Thanks!

still haven't hit the shops, in case anyone has any info...

If there are, I haven't come across them. We looked in La Sirena and a sports shop on 27 de Feb that someone suggested, but nada. Then we found one in the sports shop on the 2nd floor of Bella Vista Mall. It's a lycra top that looks very much like what we were looking for but it doesn't actually say anything about UV protection. Bought it anyway as Chirimoyito had his heart set on giving it to his Dad for his birthday tomorrow. I'll try and track down the real McCoy at my leisure - we'll probably end up getting it at Decathlon in Spain this summer.
