Belamer is a sustainable, minimalist swimwear brand founded in Barcelona, operating across Spain, France and Germany.

Their customer is a woman who values quality, design and conscious consumption. Swimwear is one of the hardest categories to size correctly, every body is different, and a generic size chart was creating friction at checkout, generating doubt and driving size-related returns.

Belamer partnered with Naiz Fit to implement a personalised size recommendation tool built around the physical measurements of their actual garments.

In 10 months of data:

• 1 in 4 shoppers used the size advisor
• size-related returns dropped 42% among shoppers who followed the recommendation.

As Berta Rosiñol, Co-founder and Creative Director of Belamer, puts it: “Naiz Fit has enabled us to offer a more secure and personalised shopping experience, helping our customers choose their size with confidence.”
