I bought this a few years ago. The square neckline makes my face look slimmer. Also, the shoulder seams start from the inside, which made my shoulders look narrower. The peplum design also helps to cover my figure. It hides my upper arms and stomach, but shows off my décolletage, which I think makes me look slimmer. The fabric is thick and sturdy. I think it's suitable for around April. The size is probably M. Please check the image of the tag.
