could use the Funky Amarylis,
in the large format, transferred onto cotton and stitch it on to the front or back of your T Shirt. I think a raggedy finish would be fun for the summer. There is also the Teeny Tiny Amaryllis pattern that could be incorporated into the outfit as pants, shorts, a jacket, anything that is playful and tropical looking. Ooh, I see some orange patent leather sandals coming.....
