I'm Madeleine!

I’m the girlfriend you text when you’re scratching your head reading labels in the grocery store, the confidante you blurt your “I can’t tell anyone else!” bathroom shenanigans to and the handy science nerd who comes through with the best cost-cutting, time-saving health tips you don’t know how you ever lived without.


I have a thing for beautiful lingerie. Maybe it’s my Franco-American upbringing but beautiful lingerie is something I’ve always loved. There’s just something special about wearing lingerie. No matter how I feel whenever I slip into something feminine, sometimes lacy, it just helps me to feel more confident and put together! It’s a simple self-care practice I give to myself! 

But for me, it doesn’t just end at beautiful lingerie. Where and how my underwear was manufactured is equally, if not more so, important to me as well. 

I like knowing who created it, where it was manufactured, what fabrics are being used. In short, brand transparency is a must for me!

My 3 non-negotiables when it comes to selecting sustainable underwear:

Breathable fabric 

When it comes to underwear, I like to stick to natural fibers (merino wool, cotton, and linen are my favorite). I stay away from any synthetic materials as much as possible. 

Growing up, when it came to underwear, the women in my life always advised me to stick to cotton. It’s more breathable, they’d say.  But, is it really? I did a bit of digging and it turns out they may have been onto something. 

Cotton, and other natural fabrics, are often recommended by doctors and  other experts because they are breathable. They also happen to be more absorbent than certain synthetic fibers which helps to reduce moisture from being trapped in unwanted places. Doing so helps to reduce the likelihood of developing yeast infections and other skin irritations. 

That being said, for my athletes out there, I personally prefer wearing merino wool over cotton for days when I know I am gonna get a good sweat in. Cotton, while absorbent, isn’t as moisture-wicking, i.e. it kind of just stays damp (just saying), as merino wool or hemp.  In fact merino wool and hemp are not only natural fabrics but they’re touted as being both moisture absorbent and anti-bacterial, which makes them great for those days when you know you’re gonna be working out or chasing your toddler around!

What to look for

Not sure what sustainable fabrics to be on the lookout for when shopping for underwear?

Here’s a brief overview of the different natural fabrics and what certifications to watch for. Conscious Life & Style has a great piece that compares the pros and cons of common textiles that I’ve linked here – How Sustainable Are Fashion’s Favorite Fibers, Fabrics, and Materials?

Conscious Manufacturing

How and where my clothes are manufactured is of the utmost importance to me. I am that person who looks at the ‘About Us’ and ‘FAQ’ pages before even looking at a brand’s apparel and goods. I like knowing where, how, and who created the products. For instance,  Were the workers paid a fair wage? Has the brand vetted their manufacturing factories? What fabrics are being used? Do they ship in eco-friendly packaging or take into account their carbon footprint?

I know, it’s a lot! Not everyone has time nor do they want to investigate fashion brands to this extent, which I completely understand. That’s why I’ve put together this sustainable underwear brand guide for you! Each of the brands listed below are transparent about their manufacturing practices, fabric choices, sustainability goals (and challenges), and are doing their best to create a product that is both as sustainable and ethical as possible. 


In case you couldn’t tell, I am not someone who spends on a whim. I am someone who researches, often hemming and hawing before making a purchase – especially when it comes to sustainable underwear, more specifically lingerie. If, like me, budget is something you consider before investing in new garments, know you’re not alone. Below I’ve listed the price range for each brand to help you narrow down your search. 

That being said, supporting a sustainable fashion brand is more than just about the garment. You’re investing in the lifecycle of the garment, supporting everyone along the supply chain from farmers to artisans to packaging and distribution. If it’s in your budget to do so, investing in a sustainable underwear brand is a good investment – for you, the makers, and the planet.

Plus, sustainable garments are often made using high-quality materials that tend to last longer. This means you may invest more upfront but less in the long run as you don’t need to replace your garments as often. Pssst…contrary to popular belief, you don’t have to throw your underwear away every year.

It’s so soft and breathable. Plus, merino wool is naturally anti-microbial and moisture wicking! Great for days when you know you’re gonna be working out or chasing your toddler! ⁣⁣Note: Although they do currently use a small amount of traditional nylon and elastane to create stretch and durability they are diligently working to create a product line that will be 100% compostable by the end of 2024. Currently their garments are a knit blend of 81% merino wool, 12% nylon, and 7% spandex.
