It happens I own this very shirt. I bought in my usual size and it fit very well. I have never measured the length, but I can do that. Width is going to vary with the size. I would buy this shirt again, (I am so taken with the beautiful shade of blue), with one caveat: wash in the machine in *cold* water, and either line dry or put in the dryer on air dry setting, NO heat. Fabric softener in the cold rinse will help keep the fabric from wrinkling so much, as will using the cool dryer. I will measure the length for you, but it may be more helpful to tell you it was not too short, in the sleeves or in the body, even when tucked in, and I am a fairly tall woman --5'7". (I always tuck, to show my belts). After my husband put it in a hot dryer, it was too short everywhere, so I bought it again, I liked it so well. (See review). Now I see that it only goes in the dryer on air dry!
OK, from the base of the collar to the bottom of the hem, it is 24 1/2 ". The sky blue and the detailing make it very very pretty.
