Here's a fun, classic style Tie Dye Tee.
What's unique about it is that it's from 2019, and specifically for girls. Tees can generally be 'anyone' item if it's the right size, but sometimes you'll find one with a 'girls cut' to the fabric (goes in at waist a bit, generally has less material for the sleeves or has a longer torso area) though those differences don't matter much. This one was sold in Forever 21 stores, specifically as a 'ladies' item. It is in adults sizes, and was about 20 dollars. It has a fun pastel tie dye swirl pattern for the whole shirt. There's neoclassic art for Sonic jumping twist, flying Knuckles, and flying up Tails. The classic logo is large, at the top.
This is nice & different, conveying 'retro' without being boring...as most shirts don't usually have an all-over background design like this one.
