Grinchmas 2025
Holiday chaos just got a glow-up. This forest-green Christmas hoodie blends mischief, style, and anime charm in one bold seasonal statement. Front and center, you’ll find a high-detail festive anime girl paired with her equally chaotic green partner in crime — a duo that’s way too adorable to trust and definitely too wild to ignore.
Crafted with warm, ultra-soft fleece inside and a crisp, vivid print on the outside, this hoodie brings comfort and attitude together in the perfect winter package. Whether you’re gaming, streaming, creating, or just trying to survive the holidays, it keeps you cozy while showing off a little “I do what I want” energy.
Sleeve Details:
Left Arm — “Too Cute to Be Nice…”
Right Arm — “Too Green to Behave.”
Bold, readable, and styled to match the artwork, the sleeve text adds extra personality and makes this hoodie pop from every angle.
Perfect for fans of anime, green-themed chaos, Christmas villains, holiday fashion, or anyone who likes their December with a little bite.
Wear it. Gift it. Start some trouble.
Tagline: Too Cute to Be Nice… Too Green to Behave.
