Case study

Filling pieces


Guillaume Philibert started the brand 'Filling Pieces' in 2009, with a vision to design a premium sneaker at a fair price point. This led to the birth of the first shoe to bridge the gap between streetwear and high fashion - the 'Low Top'. The Low Top became more than just a piece of footwear. It was a symbol of affordable, luxury design. A product that levelled the playing field. One that proved good design can unify.

Filling Pieces has grown from a one-man operation to an international team of creatives. Having originated in the garage of Guillaume's parents, Filling Pieces is now based in a historic bank building in the centre of the Amsterdam canals. Filling Pieces ensures that their design process creates the highest-quality product possible, whilst using the most sustainable production methods available.

Their main objective is helping the customers to get the right size, from the very first time. This builds confidence and it can turn first-time shoppers into regular ones, establishing brand loyalty and reliability.

If the item fits well, customers are more likely to wear them for a longer period of time. This also means fewer returns and hence, less wastage and less emission of CO2 into the environment due to transportation.


Returns is a big issue for any shop that sells online. These returns not only cause a strain in the company's profitability, but also have a drastic effect on the environment due to wastage of materials and unnecessary emission of CO2.
  • Easysize was launched on Filling Pieces in May 2020. The size recommendation solution takes less than 20 seconds, and doesn't distract the shoppers from shopping. With a few simple questions, the shopper's experience is designed to be easy, giving a precise recommendation, without asking for measurements.

  • Filling Pieces is committed to be more environmentally responsible at all levels of the company. Their focus on sustainability and responsibility, and thus, it is important for them to solve the sizing issue.

  • Filling Pieces sells everything from footwear and apparel to all genders, which is why this type of personalised SKU recommendation is even more important.

“Responsibility is one of our brand values. From that perspective, we are always looking for ways that help, support, and sustain a better world. Easysize fits right in, ensuring a better shopping experience for our visitors, that results in lower returns.”
