New e-commerce platform based on Cartalo

Marilyn is a leading manufacturer of hosiery and lingerie products in Poland. The company has been on the market for 20 years. Marilyn products are aimed at trendy and modern women who appreciate big city chic in a tasteful way. “Marilyn is synonymous with originality and modern design. The Marilyn collections embody the brand’s DNA, while the individual lines – the classic, the fashionable, the elegant Lux Line and the Patrizia Gucci designer collection for MARILYN – allow you to express yourself in a unique way.”


When we started working with the Marilyn brand, the company had a retail version of its online shop. The client decided to create a new website based on our own software – Cartalo. The new shop was to offer optimization of sales processes through a user-friendly CMS as well as greater flexibility in marketing activities. The client also wanted to introduce a loyalty program and the possibility to buy gift vouchers. One of the main objectives was to optimize the shop on mobile devices and increase the conversion rate in this channel. The website was to become more attractive, faster and more intuitive.

What we did?

Based on the results of the pre-implementation analysis and the client’s stated business goals, a completely new e-commerce platform was created. We ensured an attractive look for the shop by developing a custom graphic design with stylized product photos, new collections and inspiration from Instagram.

The shop was built on the Cartalo software we developed, which allows flexible and modular management through a user-friendly CMS panel. Now the client can easily manage a large number of promotional options such as discount codes, category discounts, free delivery, vouchers or gift vouchers. We also developed an extensive loyalty program called “Marilyn Club”, which allows customers to collect points for each order and then use those points to pay – in part or completely – for their next order.

Omnichannel enhancement mechanisms were also introduced, such as the ability to redeem gift vouchers offline and a map of brick-and-mortar shops. These functionalities have made it easier to carry out marketing activities across all sales channels.

Thanks to the possibility of adding new functionalities to the website on a regular basis, the shop allows for rapid scaling of the business (development work will continue as part of the post-implementation support).
