The fit is true to size and the print hasn't faded after several washes, which is a relief since I wear it constantly to correct people's grammar.

Wore this to my book club and three people immediately asked where I got it. The grumpy cat face is what sells it, honestly, and the cotton hasn't shrunk or faded after a handful of washes.

Stella R. ★★★★★ Sep 13, 2026

The print quality is way better than I expected — the grumpy cat's expression and the "bad grammar makes me sic" line are both crisp and haven't faded after several washes. Wore it to a family dinner and my brother immediately got the joke.
