Case Study: Monsieur TSHIRT achieves 10X return on ad spend with Facebook

Monsieur TSHIRT - Customer Case Study

Monsieur TSHIRT is a French fashion label founded by four friends known for bold, graphic T‑shirts inspired by humour and pop culture. Facing the need to boost online sales and showcase its eye‑catching designs, the company sought an ad strategy that would both acquire new customers and reactivate interested shoppers.

Monsieur TSHIRT installed the Facebook pixel to track site behavior, spotlighted its most engaging product images, and used dynamic carousel retargeting to show shoppers the exact T‑shirts they had viewed or added to cart. The campaign drove strong engagement and sales—delivering nearly a 10X return on ad spend during the Oct–Dec 2015 sales period and an average cost per click of $0.06 for the year.
