The Donna Tank Top is a fitted, semi-cropped crochet tank featuring vertical granny stitch stripes. It combines a retro-inspired aesthetic with a modern fit, making it enjoyable to make and wear for color-forward makers. The pattern is written for two colors but can easily be adapted into different color combinations—use strong contrast for a bold, retro feel, or low contrast for a softer, more modern look.

The pattern includes a separate color planning PDF with blank planning sheets for each size to help you experiment with color combinations, along with inspiration pages showcasing pattern tester projects.

CONSTRUCTION
The tank top is worked vertically from underarm to underarm as one continuous panel, shaped with rows of varying lengths. Stripes are created by changing colors every 2 rows. The edgings are added afterwards, with the straps joined during the upper edging.
