“游泳时穿戴的”可以翻译为 “worn for swimming” 或者更具体地描述为 “swimming gear/attire/accessories worn while swimming” 。不过在日常表达中，若要简洁明了， “worn for swimming” 通常就足够了，它直接传达了“为游泳而穿戴的”这一含义。
例如：
These goggles are worn for swimming to protect your eyes.（这些护目镜是为游泳而戴的，以保护你的眼睛。）
Make sure you have all the gear worn for swimming.（确保你有所有的游泳装备。）
