Definitions for "Abacost"
The abacost, abbreviation for the French "à bas le costume" (literally "down with the suit"), was the distinctive wear for men that was promoted by Mobutu Sese Seko as part of his Zairianisation programme in the Democratic Republic of Congo, between 1972 and 1990. Zairians were banned from wearing suits with shirt and tie to symbolise the break with their colonial past. The abacost was a lightweight short-sleeved suit, worn without a tie, though sometimes with a cravat.
