[speaker001:] There will be a party in my company; what shall I wear?
[speaker002:] Is it formal or informal?
[speaker001:] I guess it is a formal one because the general director will give a speech there, and most of the staff will take part in.
[speaker002:] In that case, formal suit with a nice tie will be better.
[speaker001:] You are right. What about shoes?
[speaker002:] The brown leather shoes are OK.
[speaker001:] Thanks a lot.
[speaker002:] Don 't mention it.
