It's a fashion photo by Melvin Sokolsky, taken in 1962. Looks like Soviet Red Army uniforms, but since artist is American/New York and given the year probably all prop clothing.
It should also be noted that if this was any time after 1943 or even after WWII, young men were in short supply in Soviet states. The young women's eagerness is what makes the photo interesting for modern eyes, but period eyes would understand that her eagerness is a nationwide phenomenon and a symptom of losing almost 10 million young men (10 million in uniform, in addition to the 15 million civilians dead which presumably affected men and women equally).
