The t-shirt deal of the day over at RIPT Apparel is the Super Mario Bros. – Sonic shirt called “Sonic Suit.”

The tee, by artist Gadget WK, went on sale at RIPT today, Wednesday, February 23, 2011, at midnight CST, and will continue for 24 hours from then, and once it’s over, it will not be sold on the site anymore.

The design, which has an 8-bit spin on it, was inspired by the Tanooki Suit from Super Mario Bros. 3 and shows Mario in a Sonic The Hedgehog suit.

The t-shirt is available in men’s and women’s sizes for $10 each in royal blue. Kids sizes are $15 (Boys, Girls, and Toddler in various shades of blue); Onesies are $18 (in powder blue). You can also get the design on a Hoodie for $38 (in Men/Unisex sizes in a royal blue).

What do you think of this design?
