用英语“你亲自来库尔先生的服装店看看吧！”

in person
by yourself

Come and check out Mr. Cool's Clothes Store!
这里check out有看看某个地方的意思take a look at something: to visit a place briefly (informal)
比方说：Let’s check out the new pizza place on 44th Street.
没必要专门说亲自。 如果一定要的话可以用by yourself或者in person

Come and check out Mr. Cool's Clothes Store in person!
