I bought one that I would consider black first. I am a US size 18 and the 2XL was perfect, so it is true to US sizes. The fabric weight is light enough so it is suitable for summer, but heavy enough that you don't need a tank or cami underneath.The cut is very flattering. I bought this shirt in 3 other colors I liked it so much, and all fit the same. There is a little bit of stretch to the shirt, but all that really does is make the fabric less itchy (which chiffon-like fabrics tend to be). It is comfortable, too. I highly recommend!
