I wore this for the entrance ceremony. Also great for parent-teacher meetings and observation days. It's sleeveless underneath, so you can wear it from spring to autumn depending on the inner layer. Formal suit Elegant knee-length dress The fabric is sturdy and doesn't show through even when worn alone. The A-line dress also has a slimming effect and is recommended. I'm selling it because I don't have a chance to wear it. Size 9!
