Top 8 Features to Look for in Hypoallergenic Bras

It usually starts with a little itch. Then a red mark. Elastic bands dig in. Synthetic linings trap heat. Tags rub. Then suddenly, all you can think about is taking your bra off because it’s making your skin angry with irritation. Sound familiar?

If you’ve ever dealt with rashes, hives, or sensitivity near your bra line, you’re not imagining it. Many traditionally made bras use ingredients that cause the skin to flare up. 

Thankfully, hypoallergenic bras can make a big difference. But how do you know the bra you’re buying is truly hypoallergenic? 

In this blog, we’ll walk you through 8 essential features to look for in a hypoallergenic bra, so you can feel supported, soothed, and beautifully comfortable all day long.

1 - Breathable, Moisture-Wicking Materials

When your skin is sensitive, breathability is essential. Synthetic fabrics like polyester and nylon can trap heat and moisture, creating the perfect environment for eczema, dermatitis, and sweat-induced flare-ups. That’s why a hypoallergenic bra made with natural, moisture-wicking fibres is such a game changer.

Look for fabrics like organic Pima cotton and pure silk. They’re soft, breathable, and naturally hypoallergenic, meaning they help your skin stay calm and cool, even on the longest days.

The Grace Front-Zip Bra is a perfect example. With its silk-lined cups and cotton-covered straps, it’s both supportive and soothing. 

“Beautiful, comfy, absolutely perfect. After scouring the internet for natural fiber undergarments, I came across Julie May. This piece is comfortable and I like the front zip. Thank you, Julie May, for making beautiful pieces!” - Natalie S., United States.

If you’re searching for a hypoallergenic bra that feels as good as it looks, start with the fabric.

2 - Nickel-Free Construction

Nickel allergies are more common than you might think, and bras with metal hooks or underwires can be sneaky triggers. That uncomfortable rash near your bra clasp, for example, could be your skin reacting to nickel.

That’s why every hypoallergenic bra from JulieMay uses non-metallic, acrylic components instead of traditional metal hardware. It’s a small detail with a significant impact. 

3 - Tagless Design

It’s incredible how something as small as a tag can cause such an irritating problem. For those with sensitive skin, tags can create constant friction, redness, and that maddening urge to scratch all day long.

That’s why every hypoallergenic bra from JulieMay is completely tagless. Instead of traditional tags, we use a gentle imprinting method to share sizing info.

4 - No Exposed Elastic

Elastic might be great for stretch, but it is not so great for sensitive skin. For many women, it’s one of the biggest culprits behind itching, redness, and painful flare-ups. 

That’s why a truly hypoallergenic bra should never have exposed elastic touching your skin. At JulieMay, all elastic is either fully wrapped in soft, breathable Pima cotton or removed altogether, so your skin only comes in contact with what it can tolerate.

The Valentina Back Support Bra is a standout example. It offers full-cup, wire-free support with zero exposed elastic, making it a dream for allergy-prone wearers. 

“Excellent Bra! I cannot recommend this bra highly enough. I have suffered for many years with bras as I have very sensitive skin. From the first moment I opened the parcel I knew Juliemay understood sensitive skin as there are no labels on this bra which cause me problems. If you are suffering with sensitive skin I would definitely try one.” - Linda J., United Kingdom.

If elastic has ever been your enemy, a hypoallergenic bra with thoughtful construction might just become your new best friend.

5 - Free from Harmful Chemicals

Many commercial bras are treated with harsh chemicals like formaldehyde, azo dyes, and flame retardants. These additives can trigger allergic reactions, especially for women with sensitive or allergy-prone skin.

At JulieMay, we craft our hypoallergenic bras without any of those harsh irritants. No bleach. No toxic fixatives. Just clean, skin-safe materials processed with care.

6 - Allergy-Safe Certification

When your skin is reactive, guesswork isn’t good enough. You want real reassurance, and that’s exactly what you should get with a certified hypoallergenic bra.

JulieMay bras are proudly certified by AllergyUK, giving peace of mind to anyone with sensitivities to latex, thiuram, formaldehyde, and more.

7 - Mild, Skin-Safe Dyeing Methods

Just because a bra is beautiful doesn’t mean it should come at your skin’s expense. Many traditional lingerie brands use harsh chemical dyes that can linger in the fabric and on your skin.

At JulieMay, every hypoallergenic bra is dyed using a gentle, low-impact process. We skip the bleach, avoid harsh chemicals, and produce in small batches to reduce waste and protect your skin.

The Sunbleached Floral Bra is a perfect example. We print its romantic floral design using environment-friendly technology to keep its color free from harmful dyes. 

“Finally, comfort for sensitive skin! I ordered a few bras from this company in a desperate attempt to deal with my new allergy to latex. I am glad I found them because their bras are soft, well-fitting, and, as promised, excellent for allergic people like myself. This particular bra, made of a smooth, silky fabric with a cute pattern, fits well and comfortably. I strongly recommend you consider these bra options for comfort and to avoid skin rashes.” - Mioara R., United States.

8 - Dermatologist-Approved Design

Women with allergy-prone skin deserve hypoallergenic bras that come backed by medical insight and expert approval. 

Every JulieMay bra is scientifically tested and dermatologist-approved to ensure it’s safe for even the most sensitive skin. That means fewer flare-ups, less irritation, and more comfort. Choosing a trusted hypoallergenic bra is an investment in your skin’s long-term health.

Gentle Support Starts with the Right Hypoallergenic Bra
