“I bought 2 of the Simone blouses in black and white. The size helper recommended a size M and it fit perfectly. Will look great alone, under a jacket or sweater, in both casual and work situations. And best yet -- I can wash this at home! Excellent purchase.”

I Love the fit and materials of my Numi classic shirt. It really protects the outerwear sweaters and jackets and other long sleeves from my sweat.. That says a lot.!!

”Love it! I don’t need to worry about wearing white to work. If I spill my coffee I know it will come out.”

I had a blouse that showed perspiration stains - it was frustrating to use adhesive pads. I am beyond happy with my signature undershirt. It is lightweight, comfy and works to prevent perspiration stains, just as advertised. Best part? Canadian company and made in Canada!
