请坐用英语怎么说? sit down please感觉很生硬,有更好的吗?

take a seat yourself ,please.

最正式的场合：pray be seated

please take a seat.
please have a seat.
please seat yourself.

sit down的确是命令多于请求，不太客气。

Have a seat please.

have a seat please,be my guest.

be seated
please sit down and make yourself at home
have a seat please.
