From Selfie to Size: Size recommendation for TENTIAL’s Online Shoppers using only a selfie

TENTIAL, a Japanese wellness fashion brand known for performance and recovery apparel, has successfully introduced Bodygram’s AI-powered size recommendation feature on its e-commerce platform. While the brand has long provided traditional size charts and staff fitting reviews, internal data and user feedback revealed ongoing challenges: customers were uncertain about sizing and often dropped off before completing their purchase.

To address this, TENTIAL adopted Bodygram’s Self Mode—a frictionless, camera-free sizing experience that requires only height to estimate detailed body measurements and recommend the best-fitting garment size.

Existing Tools Were Not Enough: Why TENTIAL Sought AI Support

Until recently, TENTIAL had offered:

• Standard size charts, organized by body measurements and garment specs
• Staff reviews, showing how actual employees with various body types experienced the fit

While helpful, these tools required customers to self-assess and compare abstract data to their own body — a step that proved to be a frequent point of hesitation. Especially for first-time users unfamiliar with TENTIAL's fit and sizing logic, the cognitive load was high.

Why TENTIAL Adopted Bodygram's Selfie Mode: Balancing Innovation with Practicality

When exploring sizing technology partners, TENTIAL sought a solution that could not only deliver high accuracy but also align with its user experience standards and business constraints. Bodygram's Selfie Mode emerged as the most compelling choice, offering a unique blend of technological sophistication and user-centric design.

Selfie Mode is an AI-powered sizing feature that estimates a user's body dimensions from a single front-facing photo. Unlike traditional solutions that rely on manually entered measurements or hardware-intensive scanning systems, Selfie Mode leverages computer vision and facial  analysis to infer key upper body measurements—such as chest, shoulder, and torso dimensions—using only a smartphone camera.

In the context of TENTIAL’s e-commerce flow, this technology is seamlessly integrated into the product detail page. When users tap to check their recommended size, they are prompted to take a selfie following on-screen guidance, followed by 2 questions about the height and body shape. The process is quick, requires no physical measuring tools, and produces a recommendation tailored to both the user's estimated body shape and the garment’s specific sizing data.

This approach has allowed TENTIAL to enhance the precision of its size recommendations without introducing friction into the shopping journey. By minimizing the need for manual input and eliminating operational overhead, the integration of Selfie Mode has proven to be both scalable and low-maintenance. Most importantly, it supports TENTIAL's commitment to delivering a smoother, more confident shopping experience—one where customers can focus on performance and comfort without second-guessing their size.
