Ladies, It’s Time To Refresh Your Underwear Drawer With These Top Brands

Featured Image Source

We talk about sustainability a lot here at Monet, but one category of sustainable apparel that often gets neglected is sustainable underwear brands. We’re in favor of getting the maximum amount of wear time out of your clothes, but bras and underwear are a different story — and I was yesterday years old when I learned that your bra and underwear should never celebrate a birthday.

Okay, that’s slight hyperbole. It wasn’t literally yesterday but it may as well have been, because it happened less than a month ago. I was attending a Galentine’s Day event at the local running store where the staff had enticed us with free swag, snacks, and a sale on all sports bras. Come for the brunch; stay for the bras.

I came for the brunch, scoffed at the bras. At least, at first. And then I read the flyer with that fateful fact about your underwear.

“Don’t get too attached,” the bolded letters screamed. “Your bra should never celebrate a birthday.”

Wait, what? I reacted in my head (though my bewilderment was probably palpable). Nervously, I pulled at my own stretched-out sports bra, which had not only seen one birthday, but at least three.

My bra was officially a toddler.

On that day, I vowed to refresh my entire underwear drawer. But despite the alluring discount, I wasn’t going to empty my wallet for the first pair of underwear and sports bra I tried on. While I’m incorrigibly impulsive in some ways, when it comes to purchasing apparel, I’m painstakingly meticulous with my research.

I went home and committed to my mission: compile the best sustainable underwear brands to buy from, so that my geriatric bras and underwear would never see another birthday. New year, new me.

And, hopefully, new you, too! While your sports bra is probably a baby compared to mine, it’s never too early to splurge on a new set. If you’re just as inspired to retire your old intimates, today is your lucky day. From eco-friendly brands to charity-focused companies, here are our top bra and underwear brands that will make over your wardrobe.
