Underoutfit Lifted CVR 35% and Revenue 25% With Monocle

About

One of the fastest-growing fashion brands on Shopify, Underoutfit continues to break new ground with its innovative athleisure, intimates, and shapewear products that ooze both comfort and style.

The Challenge

When Incentives Start Eating Into Margin

As a digitally native brand with a strong repeat customer base, Underoutfit relied on welcome and abandonment flows to drive growth. Incentives worked, but over time they started to eat into profitability.

Co-founder and CXO Felix Leshno wanted to keep conversions high without giving away margin. Manually testing offers and rules was too time-consuming for his team, and the results were inconsistent. With expansion and fundraising ahead, Felix began looking for a smarter way to personalize retention flows.

"A/B tests only tell half the story, and rarely can you trust your findings. You need a data-driven platform like Monocle to execute profitability at scale," says Leshno.

The Solution

Monocle's AI Journeys

Underoutfit partnered with Monocle to improve its welcome and abandonment flows. Instead of sending the same discount to every shopper, Monocle’s AI used customer behavior and purchase intent to decide in real time whether to send an offer, and if so, what size would drive conversion without cutting into margin.

This shift eliminated blanket discounts and made every interaction more targeted, lowering acquisition costs while improving profitability. Because Monocle runs in the background and connects directly with Underoutfit’s existing stack, tasks that once took hours are now automated—freeing the team to focus on bigger growth priorities. And with all results tracked in Monocle’s analytics dashboard, the team can clearly see the ROI of every flow and use those insights to keep refining their strategy.

Having total clarity into the performance and incremental effect of our strategy is almost a strange experience. The more we work with Monocle, the more ideas and concepts we want to test.

The Results

35% Higher Conversions, 25% More Revenue per User

With Monocle powering its welcome and abandonment flows, Underoutfit saw a 35% lift in conversion rate across all flows and a 25% increase in revenue per user. Instead of relying on blanket discounts or manual testing, Monocle made millions of personalization decisions automatically, ensuring every offer matched customer intent while protecting margin.

For Felix and his team, the payoff wasn’t just in the numbers. Personalization went from a heavy lift to an always-on growth driver, giving the team confidence that every interaction was optimized while they focused on the bigger picture.

We've seen enormous success with our personalization strategy since partnering with Monocle. The conversion rate and revenue increase across all our flows has been nothing short of incredible.
