I purchased this dress for my daughter to wear to a Southern spring wedding. It was very breathable cotton and she was cool and comfortable even though the day was very warm. The dress was a little loose across her chest, but that is only because she was between sizes at the time.She continued to love the dress through another three months, and it never showed signs of wear, despite it being one of her favorites. It held up very well to outdoor play, tumbling with her brother and with two dogs, and never faded or became threadbare in the wash. This is a good purchase, and I recommend it.
