About the Underwear

✔️ Particularly skin and allergy-friendly
✔️ Extremely absorbent and humidity regulating
✔️ Cool, breathable fabric
✔️ Superbly intense, brilliant colours, even after numerous washes


The fabric is made from sustainable wood and pulp (which comes from sustainable forestry 🌳).

Nearly all the chemicals used during the production of EcoVero are recovered and reused.

Compared to conventional viscose production, the production of EcoVero has 50% less emissons and takes up half as much energy and water 💧

Note to Self included on the inside for extra selflove!

About the T-shirts image

About the T-shirts

We design statement T-shirts for you.
For all Sassy Pants
For all Moon Childs
For all Free Spirits
For all who dare to stand out

Why?
We live in a society that begs us to accept, yet constantly change ourselves. A society that wants us to love ourselves, but tells confident women to sit down.

Stand up, don't shut up.
Stand out, don't back out.



All our T-shirts are Fair Wear certified, GOTS certified, Vegan & 100% Organic Bio Cotton.
All of our Printed T-shirts are handmade in Antwerp & all quality is checked until the last detail.

We sell from XS - XXXL & preach Slow Fashion by not having any products in stock.

You buy, We print - not reversed.

Hi I’m Lore,

Who am I?
I'm glad you didn't ask!

Twerkaholic, mom & overall hot mess.
My name is Lore Janssens and I swear I'm not as basic as my last name.

I am the founder & chief cheekleader of Oh Yaz! It is my mission to help you fall in love with yourself more every.single.day!

I want you to bet on yourself and expand your comfort zone.

My favorite tools are sarcasm, twerking & self reflection!
