How the clue works
The definition is C20th style, referring to the Art Deco movement of the early 20th century. The word "affected" serves as an anagram indicator, telling us to rearrange the letters of TRADE to get ARTDE. This is then followed by CO, a standard abbreviation for "company", giving us ART DECO.
