Incredible quality and design! The neon artwork is bold and nostalgic — feels like classic horror meets retro arcade. Fits perfectly and looks even better in person. Can’t wait to grab more monster tees from this series.
This tee is killer! The neon art makes the Creature look straight out of a synthwave music video. The fabric is soft, and the print hasn’t faded after several washes. Would love a hoodie version of this design too.
As a lifelong Creature from the Black Lagoon fan, I had to get this — and it did not disappoint! The neon green and purple contrast perfectly, giving it that retro-horror vibe. Super comfortable shirt that fits true to size.
Love the classic monster reimagined in neon! The colors are bright and vibrant, and the detail in the design is fantastic. The only reason I gave 4 stars is because the fit was a bit tighter than expected, but otherwise it’s awesome.
This shirt is absolutely amazing! The neon Creature design captures that perfect mix of vintage horror and 80s synthwave. The print glows beautifully under UV light, and the fabric feels soft and premium. Easily one of my favorite tees from Obtuse Mongoose.
