If you caught last week’s episode of Back To The Paddock podcast you’ll know we explored something many women haven’t thought much about—how the clothes we wear can affect our hormones.

From synthetic activewear to polyester pyjamas, many fabrics today are made from petroleum-based fibres that can leach hormone-disrupting chemicals like phthalates and BPA—especially when combined with heat, moisture (hello, workouts), or prolonged skin contact.

I shared how natural materials like organic cotton, hemp, linen, silk and wool are not only gentler on your skin but can help reduce your exposure to these harmful substances. And it turns out, this message really landed—because my inbox has been full of one question:

“Kasey, what natural clothing brands do you recommend?”

I love that you’re thinking about this! So I’ve pulled together a short list of my favourite low-tox, natural-fibre brands that I personally wear or recommend to clients.

These brands align with health & environmentally friendly values:

• Natural fibres (no sneaky synthetics)
• Low-tox processing (less chemical residue)
• Sustainable and ethical production
• Comfortable, breathable, and hormone-friendly

Whether you’re looking to slowly swap out a few wardrobe staples, update your sleepwear, or go all-in on a low-tox wardrobe, these brands are a great place to start.

Here are a handful of my go-to recommendations:

While I share all my favs within my Hormone Reset program, here are a handful to begin with:

• Organic Hemp & Cotton Activewear: Zone By Lydia  (use code KASEY10 for community discount). I love their bike shorts and crop top.
• Organic Cotton Activewear: Luna & Soul. I have their hot pants & crop top.
• Organic Cotton PJ's, Undies, bedding, Linen & Underwear: Bhumi Organics. Wait for the sales to half yearly sales to pick them up at the best price.
• Organic Cotton Bras, Undies & Leggings: pact. Their leggings are my fav out of all brands, but they are thick and quite long. I live in their comfy bralettes. 
• Organic Cotton Singlet: Neuw Denim. I have multiple colours in the Jonesy singlet.
• Organic Jumpers, PJ's & Pants: Organic Crew
• Wool Garments: Iris & Wool
• Cork Yoga Mats & Assesories: Zone By Lydia . Yep, you're breathing in what you're putting your face next to in those yoga poses. (use code KASEY10 for community discount).

The materials we wear and sleep in matter more than we think. By choosing natural fibres and supporting your detox systems (think Organic Dandelion Root Tea), you can reduce your exposure to harmful chemicals and set yourself up for balance hormones and optimal overall wellbeing.
