Nickel-Free Bras for Sensitive Skin
Nickel is the most common contact allergen in the world — and it hides in bra hooks, underwires, sliders and adjusters. If you get a red, itchy rash exactly where the metal sits, nickel is the likely culprit. JulieMay bralettes are completely pull-on with no metal at all, and across the range we use nickel-free fittings with a soft silk lining, so nothing reactive ever sits against your skin.
Why nickel triggers a reaction
Nickel allergy is a form of allergic contact dermatitis: once your immune system is sensitised, even small amounts of nickel touching warm or damp skin can cause itching, redness, blistering and dryness. It often shows up as a rash in a precise line — under the band, along a strap, or beside an underwire — matching wherever a metal part presses in. Heat and sweat make it worse, which is why it flares in summer and during exercise.
Where nickel hides in a bra
The usual sources are the back hooks and eyes, the metal underwire, the strap sliders and rings, and front-closure clasps. Even bras described as ‘coated’ can leak nickel once the coating wears. The two reliable ways to avoid it are to choose a style with no metal at all, or one made with genuinely nickel-free fittings and a fabric barrier between any fitting and your skin.
How to avoid it
- Pull-on bralettes with no hooks, wires or sliders — zero metal
- Wire-free designs so there’s no underwire near the skin
- Nickel-free hooks and adjusters where a fastening is used
- A silk-lined inner layer as a barrier against any fitting
- Breathable organic cotton to keep heat and sweat — which worsen reactions — down

Frequently asked questions
- Can a bra really cause a nickel rash?
- Yes. Metal hooks, underwires and sliders are common sources of nickel. The rash typically appears in a line exactly where the metal contacts the skin, and worsens with heat and sweat.
- Are pull-on bralettes nickel-free?
- Pull-on bralettes have no hooks, wires or sliders, so there is no metal at all — the simplest way to rule nickel out.
- What if I need more support than a bralette?
- Choose a wire-free full-cup or pull-up style with nickel-free fittings and a silk-lined inner layer, so any fitting is kept away from your skin.
