Hi, I don't usually provide feedback, but I felt compelled to do so as I spent $150 on a swim set that I can likely only wear once. I noticed that the bottom started pilling after I returned from my trip. I only handwashed it once, so I assume the damage might have been caused by sitting on a surface that caused abrasion. Still, I am quite disappointed that the ribbed material wasn't durable enough to withstand a day at the beach.
