I bought this too together with the matching shirts for a holiday in Crete in April. I knew the sea and pool maybe a bit chilly but wanted  to swim every day and didn’t want to take a wetsuit. This top was perfect as it protected me from the sun and the coolish breeze. I was in the sea or pool everyday. It looks stylish too and several people asked me where I bought it. I am taking it to Devon in May/ June when I’m sure I’ll wear it all the time as a T shirt, in the water and on the paddle board. It dries really quickly too.
