Value T-Shirt, Black, Adult S
My 11 yo wore adult XL (5’7” 165#). The 8yo is small framed. She wore adult small and tied it in the back. Dark haired male wore adult large and 5’9”, 110# female wore adult medium . Good quality dark Heather gray, Gildan brand shirt. -it was next up from basic choice and cost about $20 per shirt. Not too thick or thin. Washed and dried well, no major shrinkage. Not see-through. Can wear a bra under it fine. Screen print is just as shown and well done, front and back.
