This item is a polyester blend (somewhat stretchy material) uniform top from an unknown season of Glee. It is the top half of the William McKinley High School Cheerios Cheerleading team only. The skirt was not supplied with this top. It was worn by Becca Tobin who portrayed Kitty Wilde from seasons 4 through 6 of the series. Although, it is nearly impossible to figure out which episodes or season Becca Tobin wore this top on.
As with Brittany and Santana’s cheer uniforms from season one, this one is also made by Broadway Supply. The uniform top itself is a size 32. Because there is no red trim on the arms or shoulders it is easy to see that this was made after the first season of Glee was over.
The name Kitty is written on the size tag; a common practice done by the wardrobe department. The labeling of the item indicates that it was used during filming and identifies the character. With this information, it is assumed that it was used in various episodes throughout the series somewhere in seasons 4 to 6. It is not suspected that it was worn before those seasons but cannot be confirmed.
