THIS IS ME
I was tired of having to search for my favourite pieces again and again. When something fits us men, we want to be able to buy it again – without the fit or quality changing.
I couldn’t find that at any brand. So I founded PERPÈT.
With a fit guarantee.
Same fit. Forever. Promised.
We believe in consistent fashion
FAQs
What does “Same fit forever” mean?
Once you’ve found a piece from us that fits perfectly, exactly that fit stays in our range for good. No seasonal changes, no “sorry, sold out – it now comes in a different fit”. In five years you can reorder exactly the same size in exactly the same fit.
How do I find the right size?
On every product page you will find a size chart to help you choose the right size.
Our models Julian (1.90 m) and Wolfgang (1.86 m) both wear size L.
Niklas (our founder) is 1.79 m tall and wears size S.
What materials are used for the T-shirts?
We use only high-quality, certified fabrics – 250 g/m² premium cotton, pre-washed for maximum shape retention. Our choice of materials is made for longevity, not for short-term trends.
How do I properly care for my T-shirts?
Our T-shirts are pre-washed and retain their shape even after many washes.
We recommend:
– wash inside out at max. 30°C
- Do not bleach
This way, your PERPÈT T-shirt will stay in perfect shape for a long time and feel like new.
