Design story & product details

A pair of goggles marks the swimmer directly over the middle of the word, a small note within Birthday Swimmers, an illustrated birthday design for a Unisex Longsleeve T-shirt. Six swimmers surround the lettering in looping teal water: three rise over the top, while three sweep around the lower edge with arms extended and legs bent. White space remains clear on every side beyond the uneven outer edge of the scene, keeping the composition open around its perimeter.

The words read “Happy Birthday.” Happy is arranged in a shallow arch of tall, heavy serif capitals, moving from red to ochre, dark teal, green, and red. Birthday runs in dark uppercase serif lettering across an ochre ribbon whose ends fold back at either side.

Each figure has its own swimwear rhythm: red with cream dots, cream with red dots, blue-and-cream stripes, and red-and-cream stripes recur among the suits, while red, blue, and yellow caps punctuate the group. Cream edging and slim dark contours define the letterforms. Dense teal curls, pale cream foam lines, and outlined bubbles fill the spaces within the composition without closing off its irregular silhouette.
