Everything was perfect! Great quality, and they even accommodated my special requests and made everything possible. Super friendly service—I definitely recommend them!
I really love this sweater. The quality is great! It's soft and fluffy on the inside, and the outer fabric feels really nice. My husband really likes it :)
We wanted some cool and unique hoodies for our tennis team, and we’re always thrilled to slip into these super comfortable, high-quality hoodies after a match day. We definitely recommend them!
I ordered these wonderful T-shirts for our girls' trip to the Allgäu. It was a surprise, and they were a huge hit. Top quality, great print, fast delivery. I'll definitely order from you again 😍
I’m absolutely thrilled! My entire experience with Studio Sonntag was positive in every way. Communication went smoothly, and all my requests were perfectly fulfilled.🥰✨ The personalized design options are extensive and creative.
The T-shirt itself is high quality—beautiful and charmingly designed. I was so excited to give it as a gift!🤗 The value for the price is truly unbeatable.
I can wholeheartedly recommend Studio Sonntag.
Thank you so much for this wonderful work!💖
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.
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.🥲
Size L really runs 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!
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

The idea for Studio Sonntag came about when we wanted to cheer up a mutual friend who was going through a difficult time in his life. We designed a personalized T-shirt for him, his wife, and each of his children, featuring three matching designs.
The enthusiasm and gratitude we experienced during this process inspired us to make this opportunity for personal customization available to everyone.
