Personalized Do The Math Cookies & Calculators Ugly Christmas Cardigan, Custom Name V-Neck Button-Down

A playful holiday cardigan for math lovers and sweet tooths alike. The all-over print styles the button-up V-neck like a cozy faux-knit: green sleeves sprinkled with tiny calculators and white snowflakes; a cream-and-red chest anchored by a bold “DO THE MATH” banner, gingerbread cookie accents, Fair Isle motifs, a red plate of decorated cookies, a fraction cookie, a glass of milk with a straw, a white cookie plate, a green calculator, a ruler and a mini chalkboard showing “12 - 9 = 3.” Finished with red ribbed trim and brown buttons, plus a name banner so everyone knows whose classroom is doing the counting.
