The Patine Poppy shirt: traceability down to the last button
Organic cotton woven in Italy, made up in Portugal, milk-casein buttons produced in Italy: the Poppy shirt stakes everything on material and craftsmanship.

What it is
The Poppy shirt is the kind of garment you can wear to an important meeting just as easily as for a Sunday bike ride. Patine, the brand behind it, files it simply under its shirt category, yet talks about it as something more distinctive: the brand describes it as “the crème de la crème of shirts”, nicknamed internally the CEO shirt.
It comes in six sizes, from XS to XXL, covering a fairly wide range of body types.
So this isn’t a shirt designed for one specific use — sport, evening wear, work — but rather a piece that Patine positions as versatile, able to see out a full day without creasing.
Why it exists
The problem Patine is trying to solve isn’t so much about looks as about how the shirt holds up over the course of a day, and about traceability in how it’s made. The brand states that the shirt looks impeccable all day long, whatever the context: commuter train, bike, meeting, market. The underlying idea is that a shirt meant to move from a professional appointment to a commute or a bike ride needs to resist creasing without giving up on style.
The other issue at stake, a more structural one, concerns where the materials come from and where the shirt is made. Patine presents itself as a fashion brand that emphasises responsible materials and traceable manufacturing, with production steps spread across Turkey, Italy and Portugal. The brand also claims B Corp certification with a high score, which fits with this stated aim of being transparent about production choices rather than leaving them unexplained.
What matters
The composition is one hundred per cent GOTS cotton. This certification covers organic cotton and the conditions under which it’s processed. In practical terms, it means the raw material has followed a defined set of standards, from the cotton fields through to the finished fabric, which is reassuring when it comes to the origin of the fibre used.
The manufacturing journey is broken down into three distinct locations. The cotton comes from Turkey, weaving and dyeing take place in Italy, and the final assembly happens in Portugal. This breakdown gives a fairly precise picture of the journey the shirt takes before landing in a wardrobe, and it means you know exactly where each step happened, rather than settling for a vague “made in Europe”.
The brand states that the poplin is woven in Italy by a long-standing partner of major luxury houses. This is a claim made by Patine, but it does give an indication of the kind of textile workshop involved in producing the fabric.
The buttons are worth a closer look: they’re made from milk casein, a material produced in Italy from a raw material sourced in Ireland. This is an unusual detail for a shirt, milk casein being a far less common choice than the mother-of-pearl or plastic typically used for shirt buttons.
Finally, the measurements are given precisely for each size, both for front length and half-chest width. This level of detail lets you choose your size based on concrete reference points, rather than a simple S or M whose meaning varies from one brand to another.
Day to day
On the care side, there are two instructions. Washing is done in the machine at 30°C, inside out, a moderate temperature designed to protect both the dye and the cotton fibre. Ironing should be done on a gentle setting, at the two-dot position, corresponding to 150°C.
These two instructions point to fairly standard care, with no requirement for dry cleaning or special handling, but with attention paid to temperature, consistent with an organic cotton fabric whose quality is meant to be preserved over time.

What the brand says
Patine describes the Poppy shirt as “the crème de la crème of shirts”, a CEO-shirt nickname that reflects an ambition for the high end of the market rather than a simple basic piece. The brand also states that the poplin used is woven in Italy by a long-standing partner of the biggest luxury houses, a way of positioning the fabric’s quality against high industry standards.
On day-to-day performance, Patine promises that the shirt looks impeccable all day long, regardless of context, whether that’s a commuter train journey, a bike ride, a meeting or a trip to the market. This is a promise of resistance to creasing in specific everyday situations.
Finally, the brand claims B Corp certification with a score of 118.3 points, a figure it highlights to support its positioning as a responsible brand, alongside its traceable manufacturing across Turkey, Italy and Portugal.
Why it caught our eye
We were struck by how precisely the manufacturing journey is laid out, country by country, rather than summed up in some vague phrase. The milk-casein buttons, an unusual material for a shirt, say something about Patine's attention to detail. We also like that measurements are given size by size, rather than leaving you to guess what a simple M actually covers.
Exactly the kind of brand we’d love to come across on O!deal one day.
