Beautiful material, great fit

Couldn't find good looking skin coloured undershirts with sleeves in Europe and finally ended up on Numi's website through a blog recommendation.

Ordered few pieces and got them in less than a week and the customs was about 15% or the bill (- delivery cost of course). The size was fantastic fit, same as normally in Germany and Scandinavia (where I'm from) where people are taller and bigger than in Italy where I live. The quality is excellent and although I bought them to protect cashmere and silk work blouses and blazers, they have a very sophisticated look and I felt gorgeous trying them on just under a blazer without a blouse on top. I bought the Signature and also the Mock neck and I am most definitely ordering more.

Also love the blog and the values behind the brand. Hope we will be able to order these soon directly from Europe as well! Thank you!

so worth it!

I have been eyeing this for a while and once my size was back in stock I had to buy it. It was more expensive than my usual crop, but so worth it! This is so soft and comfortable, perfect for layering or even wearing on its own (the black kind of hides the underarm stitching). I am upset I went most of the winter without it! Only thing I’d advise is that it’s a little on the smaller side in my opinion, so if you’re between sizes I might size up. But the form-fit is great for layering, so it’s up to how you like your fit.

Love this shirt.

I love this undershirt. It fits snugly without being tight. It looks great on its own or with a sweater or jacket. Washes easily. Soft and comfortable.

About Numi

Numi was born out of personal necessity. One day our founder, Michelle, realized she never wore her favorite clothes. They were either prone to noticeable sweat stains or expensive to dry clean. When she looked for a solution, there was nothing available. And so Numi was born.

Numi is a brand that celebrates what it means to be a woman. We make consciously created products that make life a little easier for us all and inspire a culture of kindness.

Committed to Sustainability

Being mindful of our impact has always been at the core of what we do. We like to think of it as a living commitment that grows and evolves with us. This year we're taking it further. We are in the process of auditing ourselves to see how and where we can be kinder to the planet.
