try vs. try on

Hello, guys,

When you go to a clothing shop, you want to wear some clothes to know whether they suit you or not. In this situation, we say ‘try on’, like “Can I try these on?”

How about using only ‘try’? “Can I try these blouses?” Is it ungrammatical? Isn’t it used? Would you say it is wrong to say without on, “Can I try these trousers”? I’m curious.

Thank you for your reply in advance.

Many of my students try the same thing. It isn’t used, although there is nothing really wrong with it. For clothing, we use ‘try on’; for equipment, we use ‘try’.
