Indigo Floral is one of my favorites, but I now have this shirt in six colors and love them all. Depending on the color, I can wear these shirts year round in Southern California; they are neat enough to wear to work and excellent for casual wear when the temperature may change throughout the day. The light fabric is comfortable, quick drying, and you don't overheat. The long sleeves protect against sun, but you can roll them up. Speaking of the sizing -- I am 5'3" 132# and between a Small and a Medium. I prefer the fit of the Medium because I don't want it too snug across my chest, and I agree that some colors seem to run larger than others.

I bought two of these recently, size small, and they fit like a dream and look beautiful. I live in Texas and it is HOT - but I don't like wearing sleeveless shirts because the a/c is always blasting everywhere and I like some sun protection on my skin. These check all the boxes. Easy, breezy, with linen pants or jeans, I plan to fill my closet up with several more colors. I read some reviews suggesting they run slightly large - I would typically lean towards Medium but that would have been a mistake. Small was PERFECT.
