Small (2-4/6), Medium (6-8/10), Large (10-12/14), XL (14-16) Oh my goodness, y'all! I can't even with how perfect the shifter is!! I literally HAD to have it and have been counting the days until it lands at TPH!! The red piping of the v-neck and sleeves paired with the cheetah print and flattering empire waist had me seeing heart eyes immediately!! So soft with great stretch! White Birch brand. Poly/Spandex blend.
