The shirt is very comfortable to wear, has a great fit, and still holds its shape even after washing.

I designed a T-shirt for two friends to describe our friendship. I think the quality of the shirt and the print is very good. We were all really happy with it.
Viktoria P. · ✓ Verified
The quality of the T-shirt is great, and the print and designs are perfect.
Since my son is very tall and has very broad shoulders, I ordered the shirt in an oversized L.
I bought it for him as a gift from the family for his 3-month trip to Australia.
As I said, the shirt and designs are great.
Unfortunately, the shirt is way too big for him.
It looks more like a sack, unfortunately.🥲
The L size runs really huge.
Unfortunately, he can’t wear it like this.
In hindsight, I would have ordered the regular fit.
Unfortunately, I can’t send it back anymore.
That’s a real shame, but the idea and designs are great.

The print turned out really nice, and the T-shirt is good quality. I think it would be nice if there were more options for T-shirt styles—like ones with slightly shorter sleeves, a more figure-hugging fit, or a slightly shorter length. I'm giving this T-shirt as a gift.

The hoodie runs very large. Luckily, I’d checked the size chart (I was already surprised by the cm sizes for S/M/L), but the actual size turned out to be even bigger than I expected. I certainly didn’t find “Small” to be S—I don’t think that’s very helpful when ordering. Other than that, everything’s great!

Really cute shirt! Great quality and fit—the size chart was spot on.

I can't send a photo—it was a gift for my son—but the shirt and the print are great. My best wishes for your business, and may you always have many satisfied customers. Best regards, Angelika
