This postcard shows stamps featuring Belarusian national clothes. These stamps date from 1995 to 2005. Belarus also has some newer stamps showing national clothing. The stamps on the postcard and also ones issued in 2011 and 2012 are listed and shown on the Belpost page here.
Kryzhachok is a Belarusian folk dance that is performed by any number of pairs. The complicated pattern of the dance resembles a geometric ornament. The name of the dance comes from the Belarusian word “kryzh” (cross). The dancing couples form an imaginary cross by their construction, by their hands etc. Terekeme is an ancient Azerbaijan folk dance.
P.S. I just looked at the mail I got today and discovered I received an envelope with one of the 2011 Belarus costume stamps. This stamp has costumes of the Kalinkovichi region.
