„I like how the bold kiss line is bold without making the shirt look crowded. One size down was the right call for me because I prefer moderate oversize. It still reads clearly oversized, and the material feels excellent.“

„I sent the playful gym line to a friend and ended up ordering it myself. Ordered it for the print, but the cut sold me. The high collar and heavier fabric make it look much cleaner than most oversized tees. On my build: Very happy with it.“

„Mit dem Auto-statt-Therapie-Print wurde ich inzwischen schon zweimal angesprochen. Ganz ehrlich: Das ist ein echter Oversize-Fit und nicht nur ein längeres Regular Shirt. Der hohe, formstabile Kragen macht den Look deutlich cleaner. Mein Eindruck: Würde wieder bestellen.“

„The awkward dating line lands even better when someone reads it from behind. I chose the smaller size to keep the oversized shape a little calmer. It kept the oversized look I wanted, plus the fabric is lovely.“

„Der große JUST-KISS-ME-Print ist auffällig, aber trotzdem clean. Viele Shirts heißen oversized und sitzen dann fast normal. Dieses ist wirklich weit, hat aber genug Struktur und hängt deshalb nicht wie ein Sack. Qualität und Kragen waren deutlich besser als erwartet.“

„The half-asleep line is oddly specific, which is exactly why I picked this version. A lot of tees are labelled oversized but fit almost regular. This one is properly roomy and still has structure, so it does not hang like a sack. The quality and clean collar were much better than I expected from an online brand.“

„I sent the gym-motivation slogan to a friend and ended up ordering it myself. I originally clicked buy because of the back print. In person the best part is the cut: broad through the body, solid fabric and a neck that sits high instead of stretching out. I ordered another colour after the first week.“
