Jumpsuits are one of the most popular fashion items in the world competing with dresses. The number one reason, mostly, women decide not to wear a jumpsuit is the lack of their functionality. Dressing, undressing, adding or removing one layer is impossible without removing all your clothing. If you've ever worn a jumpsuit, you know how challenging it is to use the restroom, or remove a layer when it's too hot; especially when you decide to wear a blazer or jacket on top. To solve this problem, we created the Zip-on jumpsuit. The top and bottom pieces of this garment are attached through a zipper that goes all around the waist. This improvement allows you to easily remove only one piece at a time. The pieces can be replaced with other styles, for example if you replace the pants with a skirt, the piece becomes a dress, the most popular choice there is. We bring practicality to fashion, without compromising on style. We focus on quality and circularity. An important aspect we focus on is fitting and sizing. Our sizing allows for sizes S-M and M-L to share the same measurement at the waist, for maximising the fitting range of women in the current time. Our jumpsuits are made out of qualitative organic fabrics, made by fairly treated workers. Our business is feasible and scalable. Our Zip-On jumpsuit is practical, comfortable and modular. It is One piece, but two.
