A vintage-style t-shirt design with a retro sunset gradient background featuring horizontal stripes in yellow, orange, and red. The center of the design contains a large white pi symbol (π) with a distressed texture. Above the pi symbol is the text "FLUENT IN" and below it is the text "MATH AND SARCASM" all in white distressed lettering with a vintage aesthetic. The text is arranged in a circular pattern around the central pi symbol. Two white stars flank the text at the bottom. The entire design has a weathered, vintage appearance with a black background. The text and design elements have a worn, textured look that gives the impression of an old photograph or vintage poster.
