I bought this last June and my child wore it during the summer. It was perfect for the hot weather, and they could spend the day in just this one outfit. It's a cool, mesh material, so it seemed nice and breezy. I'm selling it because my child has outgrown it! The gingham check one has some stains. The dark green one has some sun damage on the shoulders. It's sized for 6 months and up, but my child was wearing it from around 3 months old.
