Thank you, everyone. I have had fun looking and shopping. The HerRoom site has a lovely Ann Cole top but it more than I can justify spending for this purpose, unless I make a birthday present to myself. Maybe I will. . . .
I had not thought of REI but I found some good options there. I was wondering what to do with my dividend, so this might be the answer.
I lucked into a sale at Lands End, 7 hours before the promotion code expired, so I ordered 3 to try, all under $20.
I wasn't planning on taking a swimsuit on this trip, but then I looked again at the itinerary ( one part is an REI Adventures hiking trip in Spain) and saw the plan includes time to swim while we are hiking the Costa Brava coastal path, as well as free time in our village ( Cadaques) . I know the water will still be quite cold at the end of May, but that won't deter my husband, and I like to at least wade while he swims. After that we will be on the Dorset coast for more walking, and our accommodation has a nice outdoor pool ( hopefully heated). So I think it will be worth taking the swimwear.
