How to Choose the Right Underwear: Materials, Pros & Cons

Let’s face it — we wear underwear every single day, but most of us don’t really think about how to choose the best pair. Whether you’re looking for something comfy, sexy, breathable, or eco-friendly, the right underwear makes a big difference in how you feel.

So, how do you pick the right underwear? One of the most important factors is the material. Today, we’re breaking down the most common underwear fabrics, their advantages and disadvantages, and tips to help you make smarter, more comfortable choices.

🌸 What Should You Consider When Buying Underwear?

✅ Size & Fit — Too tight, and it cuts into your skin; too loose, and it rides up or doesn’t support you. Always check size charts and, if possible, try before you buy.

✅ Style — Briefs, hipsters, thongs, boyshorts, boxers… The best style depends on your outfit and personal preference. For example, seamless thongs work under tight pants, while cotton briefs are great for everyday comfort.

✅ Material — This is where comfort, breathability, and sustainability really come into play.
