The denim shirt
Coming out in November 2023
We use organic cotton because so-called “conventional” cotton is a disaster for insects, birds, and farmers. Read more in this article.
235 g/m² is equivalent to 7 oz, a density** **that is slightly higher than average. This fabric is both durable and comfortable.
With** **room in the chest, room for the hips (thanks to a rounded cut on the sides), and the right length so you can wear it tucked in or untucked.
This shirt is made in Portugal at the Supercorte factory, with which we have been working since 2017.
Worn, tested, and approved by thousands of customers, this shirt is the result of a balance between quality, ethics, and price that we now consider optimal.
For example, we could opt for a reactive dye, which doesn’t fade, but we would lose all the beauty of the denim’s patina.
Techniques That Ensure Quality
Thick buttons
We chose thick resin buttons that won’t break in the washing machine, unlike those made of wood or mother-of-pearl.
Just in case, a spare button is sewn onto the care label.

To ensure that the buttons don't come undone, we've reinforced their attachment using Ascolite technology, a process that involves wrapping the base of the button with a heat-sealed thread.

This shirt has been stabilized and pre-washed at the factory to prevent it from shrinking when you wash it at home (with cotton clothing, most of the shrinkage occurs during the first wash).

Hi (cow) girl
For this denim shirt, we found a beautiful Italian denim made from 100% organic cotton, available in two shades: “stone” blue, like in Westerns, and a faded “bleached” blue that goes with everything. Yes, this shirt is beautiful, but it’s also sturdy: the fabric is dense (235 g/m²), the buttons are thick, and their fastenings are reinforced.
In detail
Candiani Denim
An Italian manufacturer renowned for the quality of its denim fabrics.
Indigo dye
A dye known as a “pigment dye” that fades with each wash, giving the fabric a unique hue.
Chest pocket
To store your lasso.
Rounded cuffs
The sleeve cuffs have a curved cut: this means they wear out less over time and with repeated washings.
Horizontal buttonhole
Leave just the last button undone to make room for your belly.
How to Wear It
A few ideas if you're stuck
Composition
100% cotton
Origin and Certifications
- Cotton: India
- Weaving, dyeing, and spinning: Italy
- Manufactured in Portugal
...manufacture in Portugal instead of France? Of course, manufacturing in Portugal allows us to sell at lower prices. But it’s also easier to produce high-quality items there: in the 1980s, when France outsourced its manufacturing, Portugal strengthened its own. That said, others besides us manage to make denim shirts that are 100% made in France, like Atelier Tuffery.
... does the cotton come from so far away? Cotton always comes from far away. While a few die-hard Gauls manage to grow it in their fields, cotton farming is a niche industry in Europe. For this shirt, we have no control over the geographic origin of the cotton, since our weaver selects the yarns.
How This Product Will Age
How do we know this? We ask our customers for their feedback on the product one year after purchase. And if the product is less than a year old, we provide our predictions based on some unsolicited feedback and our experience with similar products.
This shirt will age beautifully—that’s the great thing about high-quality denim: it develops a nice patina over time. And we’re even more certain of this now that we have the benefit of hindsight from the men’s version (made from the same fabric). Like any denim shirt, it will fade with each wash, especially in high-friction areas like the elbows and collar.
Care Instructions
It's 100% cotton, so it's machine-washable at 40 degrees and can be tumble-dried. But it's best to wash it at 30°C and let it air-dry: it's just as effective, much more eco-friendly, and will extend its lifespan. And be sure to unbutton the collar and cuffs to minimize friction and prevent them from wearing out over time (as shown here).
The stone-washed and bleached versions are indigo-dyed and will fade slightly with washing—this is completely normal.
Our best tip to avoid getting your denim shirt back too wrinkled and to make ironing easier: spin-dry on low speed (600 rpm max) and hang it on a hanger while it’s still damp. By the way, ironing is an art we can’t teach you in just a few lines— here’s a great three-minute video demonstration. Don’t forget to always iron your shirts inside out and at a low temperature to minimize damage.
Environmental Cost
This environmental cost is calculated using the official methodology of the French environmental labeling system (to be rolled out starting October 1, 2025).
The label above shows the product’s environmental cost according to the official French environmental labeling methodology. This represents what its production “costs” nature when considering its impact on climate change, ocean acidification, its toxicity to freshwater, and so on. Currently in use in the textile sector, this label should soon appear on many everyday consumer products (food, cosmetics, furniture, etc.) to help you make more eco-friendly purchasing decisions.
The denim shirt therefore has an environmental cost of 488 impact points*.
By comparison, a garment of equivalent weight made of 100% conventional cotton, manufactured in Bangladesh and sold by a fast-fashion brand, has an environmental cost of 2,024 points*.
Why is there this difference? Here are the main reasons:
- Countries of origin: Manufacturing in Portugal or France requires less fossil fuel energy than in Bangladesh (one of the leading producers of low-cost clothing). As a result, this more local manufacturing reduces the impacts on climate change, ocean acidification, and resource depletion.
- The material: Organic cotton has a relatively low environmental impact compared to conventional cotton, particularly because it uses few pesticides (and thus poses a low risk of toxicity to freshwater) and is biodegradable (and thus causes fewer issues related to microfibers or end-of-life waste).
- Sustainability: Fast-fashion retailers encourage purchasing—in particular by rapidly refreshing their collections and offering a vast number of styles—and they discourage repairs by charging rock-bottom prices. This, in turn, increases the number of garments sold per person and reduces the number of times a garment is worn. In contrast, at Loom, we’ve chosen to adopt business practices that encourage our customers to keep their clothes for as long as possible.
Even though we've done everything we can to minimize it, this product's environmental impact is not insignificant. So before you buy, make sure to get the most use out of your clothes.

Please note: The number of points is not always exactly the same on Ecobalyse (whose methodology changes regularly) as on the official environmental label (based on Ecobalyse version 7.0).
Reviews of this product
The standard practice is to send review request emails a few days after the purchase. We wait a month—the minimum amount of time needed to form an informed opinion.
Customer Review Policy
When do you ask customers for reviews?
We’ll send you a review request one month after we receive your order. We believe this is the minimum amount of time needed to have worn and washed an item several times and to form a truly informed opinion. After that, all your reviews are published within a week, whether they’re positive or negative.
Do you request reviews for 100% of the products ordered by customers?
We used to do that at first, but then we realized we were starting to send way too many emails to certain customers who shop with us regularly. In short, we were spamming them a bit. Plus, it was starting to take the team way too much time to respond to reviews—since we want to reply individually and privately to almost everyone who leaves us a review. Today, we no longer ask for reviews on products that meet the following two criteria: 1/ There are enough reviews posted on the site for potential buyers to form an informed opinion about the product. 2/ We on the Loom team have read enough reviews to understand how to evolve the product into the next generation.
Just a quick thought: What proof is there that we aren't manipulating reviews by giving 5-star ratings to everything?
Honestly: nothing—we’re just giving you our word. Just like with everything else, actually: where we manufacture our products, where our wool comes from, our lab test results, and so on. The only times we might edit what you write is if your message contains spelling mistakes (and even then, quite a few slip past us) or if it’s racist, homophobic, etc. (but that’s never happened so far).
Asking for feedback after just one month isn't enough to know if the clothes are really durable, is it?
You're right—that's why we send you another email asking for a review one year after your purchase—we even ask for a photo to see how your garment has aged. We use the responses to improve our clothing and to provide information on “how this product will age” on our product pages. To avoid unnecessarily bothering our customers, we don’t ask for reviews on 100% of the products ordered: as soon as we have enough data to understand where we can improve, we stop asking for reviews after one year.
