The jersey of this period was short-sleeved with no trim except for a dark blue collar. Stockings were dark blue with red stripes and the cap was blue with a white "P". A "PBC" monogram signifying Pittsburgh Baseball Club was also added to the left sleeve later in the decade.
The regular collar was replaced by the short, stand-up "cadet" style with a button collar. Pinstriped material was also introduced. As the team nickname became more accepted, "Pirates" was displayed in capital letters down the button lapel (1912). The cadet-style collar soon gave way to a tapered collar extension, but the buttonlapel remained solid dark blue with white buttons and a "P-P" straddling the top button (1913-14). Later in this decade, the cap had piping and also included a "P" in white or red.
Standard white uniforms were worn at home and gray on the road with simple graphics and solid colors. The 1925 and '27 championship teams wore the standard capital ?P? on its sleeves but not on the jersey. A red ?P? was also placed on the solid blue cap.
