This is a navy blouse. It has a relaxed and long fit, so I used it for office casual wear during my pregnancy. It was quite useful right up until my due date. The sleeve length is somewhere between five-tenths and seven-tenths of the way down the arm. I'm not very knowledgeable about clothes, but it might be a tunic. It's not specifically a maternity blouse, so I also recommend it to those looking for a relaxed navy blouse. Thank you for looking. Size...FREE SIZE Sheerness...No sheerness
