Underboob Sweat and Skin Health: Choosing the Right Bra
Let’s talk about something no one wants to deal with (but nearly every woman does): Underboob sweat.
It’s uncomfortable, irritating, and all too common, especially during warm weather or workouts. Left unmanaged, it can lead to skin rashes, chafing, and even infections that impact your daily comfort and confidence.
But here’s the good news: the solution doesn’t have to be complicated. Choosing a bra that breathes, supports, and respects your skin can make a big difference. Especially now that summer has arrived!
What Causes Underboob Sweat?
Underboob sweat happens when heat and moisture get trapped beneath the breasts. It is often the result of tight clothing, warm weather, and your body’s natural cooling system. The apocrine sweat glands, found in areas like the underarms and breast region, release a thicker, protein-rich sweat that mixes with heat and friction to create the perfect storm for discomfort.
Bust size and breast shape can also play a role. Women with fuller or lower-hanging breasts often experience more perspiration in this area. Add synthetic fabrics into the mix, and the problem quickly worsens. These materials tend to trap heat and moisture rather than release it, leading to more sweat, irritation, and even odor or rashes. Ouch! Poorly fitting bras only make things worse.

Tips to Minimize Underboob Sweat
Managing underboob sweat takes more than a quick fix. It’s about building mindful daily habits that support your skin from the inside out.
Start with your wardrobe.
Swap out tight-fitting, synthetic tops for loose, breathable pieces that allow airflow. Stick with natural fibers year-round, like the organic Pima cotton and silk blend found in JulieMay’s collection of bras.
When sharing what she loved about the Valentina Support Bra, Pamela L. shared that it’s “beautifully made and so very soft and comfortable. With larger cup sizes it's often hard to find anything but industrial-looking bras, but this bra is very feminine. Great support, without underwire, yay! Washes well too.”
Our Valentina bra offers luxurious comfort and gentle support, crafted from organic Pima cotton and featuring a 100% pure silk inner lining. Designed with shaped three-part cups and a supportive side sling for natural separation and forward projection, this non-padded, wire-free bra also features smoothing coverage under the arms and across the back. Wide straps enhance comfort and evenly distribute weight for larger breasts, while the breathable, hypoallergenic fabric makes it ideal for sensitive skin.
Stay hydrated.
It may sound counterintuitive, but make sure you drink enough water. The International Hyperhidrosis Society reminds us that sweat helps regulate our body temperature when it’s hot, acting as a natural cooling system. To keep it functioning effectively, it’s essential to stay well-hydrated.
Keep breasts lifted off the chest.
Lifting the breasts slightly away from the chest can make a big difference when it comes to reducing underboob sweat. A supportive, well-designed bra helps prevent skin-on-skin contact, allowing air to circulate more freely and minimising moisture buildup.
The Grace Peach Silk & Organic Cotton Lace Front Zip Wired Bra does exactly that. With its breathable construction, which utilizes organic Pima cotton and 100% silk-lined cups that wick moisture away from the skin, it’s ideal for sensitive skin and humid days alike. The full-cup design offers gentle lift and secure support (without harsh elastic, padding, or irritation), helping you stay dry, cool, and comfortable all day long.
Maintain good hygiene.
Make it a point to shower regularly and gently cleanse the underboob area to remove sweat and bacteria before they irritate your skin. For added protection, try Evenly Dusting Powder. It’s a talc-free option that helps absorb moisture without clogging pores.
Wear a breathable bra during workouts.
During workouts, wear a breathable bra, such as the Fuchsia Back Support Bra, and always change into a fresh one afterward. Trapped sweat is a fast track to rashes and discomfort. And we definitely want to avoid that.
Designed to feel like a second skin, our Fuchsia bra features side and back smoothing, gentle front gathering to enhance your natural shape, and a pull-over, non-padded style ideal for sensitive skin. Recommended by a breast surgeon, this bra is soft, breathable, and ideal for everyday wear.
“Superbly made, so comfortable. I'm a 36E usually and the size 14 fit perfectly. Im also allergic to synthetic fibres, including elastane, so this really is a joy to wear. No irritation at last. Thank you Julie May, you really are a life-saver.” - Sarah A., U.K.

Why Fabric Choice Matters when Choosing the Right Bra to Manage Underboob Sweat
Not all bras are created equal, especially when it comes to managing underboob sweat. Synthetic fabrics like polyester and nylon may offer stretch, but they tend to trap heat and moisture against the skin. That trapped sweat becomes a breeding ground for irritation, odor, and even infection.
Natural fabrics like organic Pima cotton, on the other hand, are breathable by design. Paired with JulieMay’s 100% pure silk linings, these materials allow airflow while gently wicking away moisture. This thoughtful combination helps reduce underboob sweat and keeps delicate skin dry, cool, and calm.
For women with sensitive skin or those recovering from breast surgery, these hypoallergenic options can truly save the day. Just ask Jennifer K., who found relief in the Georgia Silk and Organic Cotton Back Support Bra.
She shared, “I had breast cancer and surgery Feb 2022 on my left breast underneath where the band hits. Wires and other bras have been super uncomfortable. But JulieMay Bras have saved the day for me! Life is too short to be uncomfortable. I love this bra because it is soooo comfy. I wear it with sweaters and loose blouses.”
Featuring a wire-free, non-padded design with 100% pure silk lining and soft lace accents, the Georgia bra offers full back coverage and wide straps for gentle support and smoothing. Recommended by a breast surgeon, this bra is hypoallergenic, and the pull-on style is ideal for individuals with sensitive skin and those who struggle with hooks and clasps.
Stay Cool, Dry, and Comfortable This Summer with the Right Bra
Yes, underboob sweat is a nuisance. But it’s also a signal from your body. One that says: I need breathability, softness, and support. Reaching for the right bra can help you manage underboob sweat and respect your body’s needs all summer long.
JulieMay’s collection of organic Pima cotton and silk bras is thoughtfully designed to reduce underboob sweat and soothe sensitive skin. Explore the collection and find breathable, cooling comfort that lasts.
