Czech Rep.:

It can be difficult to define a common approach to business attire in the Czech republic and will probably dpend on the type of busines you are dealing with.

On the whole, unless dealing with finance instituations or law firms, business dress tends to be realtively informal with ties and jackets not obligatory.

Always check in advance before travelling if you are not sure of the correct dress code and remember to factor in seasonal changes as winters can be hard and summers hot.
