Sleeved UPF SWIM WEAR

I have recently had a Lumpectomy with some Lymph Nodes removed, followed by Radiotherapy. The advice is not to expose the chest and arm area to sun rays for at least a year. We already had a planned holiday in the sun! I looked around for suitable swim wear that was both attractive and suited my purpose. Did not find anything I thought O.k. I have a bikini that I like wearing so I then looked for something to wear over the top. I found a top by Berghaus with UPF OF 30 that cost me £25. It was in a pretty two tone blue with a shaped neck line. Have just returned from my holiday and have to report that it worked really well- not too clingy, dried quickly and could be removed to sit in the shade. I put sun cream on before wearing it to add to protection. Not exactly what I wanted BUT it meant that I could enjoy a swim in the open air. Any thoughts on the subject?
