This type of shirt has become standard all over Ukraine. Mean wear it with modern slacks when they wish to be somewhat formal, or show their identity, or participate in a festival, and it is often worn with a suit. It is also used in stage costume, or by local performing groups. The only current distinction between regions is the type of embroidery, of which Ukraine has a tremendous variety. But even this is often ignored. The older traditional shirts tended to have embroidery which stopped halfway down the front, or even shorter, but the modern shirt usually takes the embroidery to the beltline. The embroidery varies in width from about a centimeter for each strip, to wider than the collar. This dates back, more or less to the 1950's, about the same time that women started cutting the chemise in two parts horizontally, to be able to wear the embroidered shirt with modern clothing. Here is a photograph showing a man wearing this type of shirt. Note that his does not actually have a cuff. Both cuffed and cuffless shirts are known.. You will also notice that his shirt has the traditional constuction, with the so called 'drop shoulder'. [the only kind of sleeve that anyone wore until recently, but it has become necessary to explicitly tell people that no, you don't need that curved seam at the point of the shoulder].
