Sustainable loungewear has become a staple in my wardrobe over the last few years. Despite some resistance when it first sprung onto the fashion scene, loungewear has become what I reach for when working from home, not to mention lounging around the house in!
However, as with all clothing, finding good sustainable loungewear is tricky. I want to know that it is made fairly, with sustainable materials and practices, and that the garments will last and last. And if you’re here, I bet you’re thinking the same! Here’s what to look for when you’re searching for sustainable loungewear…
6 Things To Look For In Sustainable Loungewear
To help with this guide, I spoke with Gabriella Diana, CEO & Founder of Onesta, a luxury womenswear brand that started off exclusively producing sustainable loungewear. According to Gabriella, the seven things to look for in sustainable loungewear are:
- Ethical employment
- Sustainable materials
- Slow production
- Inclusive sizing and design
- Transparent pricing
- Long-lasting clothes
- Circular practices
These are all great pointers to look for when shopping for loungewear, and sustainable fashion more generally. In practice, Onesta goes above and beyond most sustainable fashion brands, and really does lead by example, in both their loungewear and womenswear.
What’s In My Loungewear Drawer
Onesta Valerie Set
I love the style and comfort of Onesta’s loungewear. The grey set I’m wearing in thes photos accompanying this guide is their Valerie Sweater and Valerie Joggers, both in the shade Sleet. I’ve worn this set religiously for four years now, and can say that it’s still super soft and comfortable to wear, doubling up as pyjamas during the wintry months.
Organic Basics Cotton Weave
My next favourite set has to be the Organic Basics True Knit Sweater and matching Wide Leg Pants*. I first wore this set in Copenhagen, and it’s quickly become my favourite loungewear set for travelling in. The top and matching trousers are made of organic cotton, knitted together for a comfy, vegan alternative to wool.
Tentree Hoodie & Sweatpants
My final loungewear set comes as a hoodie and pair of sweatpants from Tentree. I ordered this set back in early 2021, during the lockdown, and lived in it for days at a time! It’s now also doubling as running gear – the hoodie is cropped and lightweight – and pyjamas for colder nights.
