更少的衣服用英语可以说成 "less clothing" 或者 "fewer clothes." 这两种表达方式都是正确的。

"Less" 是一个形容词，意思是 "较少的"。它可以用来修饰不可数名词，比如 "less sugar" (较少的糖)，"less water" (较少的水) 等等。

"Fewer" 是一个形容词，意思是 "较少的"。它可以用来修饰可数名词，比如 "fewer apples" (较少的苹果)，"fewer cars" (较少的汽车) 等等。

下面是一些例句：

"I'm going to wear less clothing today because it's hot outside." (我今天会穿更少的衣服，因为外面很热。)
"I think we should pack fewer clothes for our vacation. We can do laundry while we're there." (我觉得我们应该为度假打包更少的衣服。我们在那里可以洗衣服。)
"I have fewer clothes in my closet now than I did last year." (我现在的衣柜里的衣服比去年少了。)
