Premium tights like you've never experienced before. This is our innovative and stylish take on the classic 20 denier tight that all women should have in their wardrobe. Durable, comfortable, sensual and sustainable. 

Size guide 

We offer our tights in 4 sizes: S, M, L, XL. 

We know it’s infuriating to buy tights and never knowing if they are going to be the right fit. So we are in the process of creating an advanced technical size chart, so you will know exactly which size to select. 

In the meantime, during this pre-order phase, you do not need to select your size. We will email you our size guide when it’s ready so you can select the right fit and receive your tights on time in September. 

If you are  still unsure about the right size for you, we will happily guide you as best we can, you can contact us at

Billi’s Care Routine

We strongly recommend hand washing your tights, it should take no more than 60 seconds! Otherwise, machine wash at no more than 30C and in a mesh garment bag. 

Your tights should be looked after the same way you care for your most loved pieces of garment, so we have created a care guide here that will extend the durability of your tights. You’re welcome!
