Great shirts

Love the undershirts. I wear them at work all day to prevent sweat stains. They worked great, even in 90° weather.

Wonderful piece!

This signature piece is so well made. It’s soft and not too restrictive but really smooths the lines!

Changed my outlook on shopping

Today I wore a mustard yellow shirt. With tight sleeves. Any lady who sweats knows how big of a deal that is. Yellow! Tight sleeves! In Floria! A recipe for disaster. Yet not with Numi. I kept going to the bathroom to check for sweat stains, and I found none. I was online shopping tonight and found myself looking at a dress. "Can't do it, the fabric will sweat through," I thought. But then I caught myself--it won't sweat through if I have on my undershirt! This product has truly opened up a world of options for me.

Sweat is a very embarrassing, personal thing. I've considered botox to stop it. I can tell this product will truly make me happy.

Amazing

Completely stopped me from sweating through, even on high stress days. I have always been an excessive sweater, and now I am so excited to buy clothes in colors and not just black!

This shirt is a lifesaver!

I was always so self conscious about what I was wearing for fear of showing sweat stains. This shirt has given me the confidence to wear the clothes I love without worrying. The shirt was a bit more snug than I expected, but I'd rather have it tight so you can't see it under my other shirt, so I don't mind. I will definitely purchase another to have when this one is in the wash!

NUMI- New Me!!!

LOVE LOVE LOVE!
Numi has changed the way I feel! I am fresh as a daisy and don't have to worry about sweat showing through my tops. Perfect fit, and totally discreet! No bulking or bulging.
