This is a cotton easy tee by UK brand Toa.st. It's new with tags - the only reason I never wore it was because the color on the website showed a bright yellow color, but the shirt I received was more of a yellowy chartreuse (the photos listed here are much more true to color than if you look on the Toast website). It has drop shoulders, and no shoulder seam. It's meant to be oversized. Measurements (taken while laying flat): Length: 24.5 inches Bust: 25 Waist: 25.5 Sleeve length from neck: 11 Sleeve width: 7.5 Size L Material: 100% cotton Care tag: Cool delicate machine wash From a non-smoking, dog-friendly house.
