Purchased at a Mamaway store in Taiwan (similar to Akachan Honpo in Japan). I fell in love with the pattern, but unfortunately, my child ended up using formula, so I never had the chance to use it. Also, I'm no longer at an age where I'd show off my upper arms... The color is navy blue, and the lower body has a lining, so it's not see-through. The length reaches my knees (I'm 163cm tall). It has an elastic waistband. It can be worn as a regular dress. I will wash it before I give it to you.
