What I Consider Before Buying

I always pay attention to the quality of the TMNT details. I want the colors to be bright, the shell design to look clear, and the stitching to be strong.

Finding the Right Size
Sizing can be tricky, so I always compare my measurements with the seller’s chart. I usually think about whether I want a snug fit or a looser, more relaxed feel. If I plan to wear it over pajamas or use it as a costume, I often choose a slightly larger size for extra comfort.
