This is a Ritali dress. The size is XS, but it has a loose fit, so it feels like a size M. Colors: Blue Navy, Pink, White, Black 3/4 to 7/10 sleeves, perfect for this time of year. The darker colors have slightly transferred onto other areas. As shown in the photos, it's a patterned design, so it's not very noticeable.
