Gap XL Extra Large Top.  I'm so bummed my first picture is so blurry !  It's such a cute top and normally I can wear XL with Gap but this has been sitting for a long time :(  The armpit to armpit measures approx 23  inches and the length is approx 28 inches in the front and 30 inches in the back. If you have any questions please let me know. Thank you for looking !
The front of the shirt picture is horrible and I'm not sure why but it's wayyyy cuter in person !
