Premium fabrics
We use 100% cotton with a fabric weight of 250 g/m². Fabric weight describes how much a fabric weighs per square metre. We chose 250 g/m² deliberately – it gives the fabric noticeable quality, stability and durability without feeling heavy.

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?
Every product page has a size chart to help you choose the right size. Because our fits stay the same, you only need to find your size once – every future order will fit again.
Our models Julian (1.90 m) and Wolfgang (1.86 m) both wear size L.
Niklas (our founder) is 1.79 m 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 care for my T-shirts properly?
Our T-shirts are pre-washed and keep their shape even after many washes. We recommend washing them only according to the care label: at max. 30 °C, inside out, without bleach, with similar colours.
Where are your T-shirts made?
All our products are made 100% in Portugal, by selected production partners with whom we maintain long-term, personal relationships. These workshops meet high standards of quality and fair working conditions.
Can I change or cancel my order?
Yes, simply email us at info@perpet.men. Shipping and returns within Germany are free, and every parcel includes a return label. For orders outside Germany, shipping costs are shown at checkout; in this case the customer pays for returns.
How long does shipping take?
Delivery time depends on your location. Within Germany, shipping usually takes 1–3 working days. International orders may take a little longer.
Can I exchange or return my pieces if they don’t fit?
Yes, we offer a 14-day return and exchange option. The pieces must be unworn and have the original tag attached. You’ll find detailed information in our refund policy.
Can I buy PERPÈT in a store?
