Perfect for Arizona and exactly what I was looking for. This type of material is my favorite. It's very light, breathable and doesnt stick to you when it's hot. I love mini dresses with sleeves because I have chubby arms...and it's very loose around the arms. I normally wear either a 1x or 2x, depending on the outfit. I got this in a 2x, and could definitely have gotten away with the 1x..but either way the fit is still perfect!!!!
