Here is a rather stylish 3 Piece PJs set exclusive to Kohls Department Stores.
This is a summer 2020 item, probably in the boys section. If it's too small for teens/others, it'll be a shame too because it's rather stylish. They've taken the modern characters & 'splashed on' shading for the faces to give them a unique look that has not been done before. The short sleeve pajama top has that done in gray for the full color modern/large Sonic. The pants have rows of gray faces for Sonic, Tails, and Knuckles (all faced forward) with the same effect applied to those. It also spells out his name in green between the rows. The sleep shorts (for warmer weather) are navy blue with green stitch borders & 1 small Sonic logo tag at the waist bad. It's a nice looking set....too bad it probably won't fit anyone but kids.
