FAQs

Women need sweat-proof undershirts to prevent visible sweat stains on their clothing and to stay dry and confident throughout the day. It can also help prolong the life of outerwear by reducing the need for frequent washing.

Our sweat-proof undershirts were created to be the perfect base-layer for day-to-day dressing. They feature our innovative Contemporary Cotton underarm shield, designed to wick and absorb moisture to prevent sweat stains from showing on your clothes. With the body made from a breathable TENCEL™ fabric, our undershirts also help to regulate your body temperature, ensuring all-day comfort.

We recommend using the size guide (featured on every product page) to determine the best size for you.

Each size guide features a sizing chart and instructions on how-to-measure the item. Generally, we recommend ordering our Essential Undershirt collection in your regular size for the perfect, snug fit. If you prefer a more relaxed fit, we recommend sizing up. If you’re still unsure about sizing, send us an email at customercare@wearnumi.com.

Absolutely! All our undershirts are machine-washable and dryer safe. Simply wash them cold and with like colors.
