Can you find this OLD movie?

So I’m trying to find this movie it looks to be around 1940s and it’s a romance between a guy and a girl. The guy was or is or will be part of the military (he had the uniform) the girl had an apartment. In the apartment was a grand piano and on a step up to the left of the piano was a folding screen. I think the furniture had little flowers on it. At the end the woman gets a part in the play carmen. She’s the lead. The extras in the back for the play looked like little tin soldiers in button down uniforms and plumes on their helmets.
