01 / The Challenges

Key Problems & Obstacles

Critical eCommerce barriers the brand needed to overcome to streamline bikini discovery and maximize order value.

! Bikini Separate Pairing Friction: Shoppers struggled to coordinate matching tops and bottoms when forced to navigate between separate product pages.

! Sizing & Coverage Uncertainty: Sizing hesitation (top vs. bottom fit mismatch) caused high mobile cart abandonment and customer returns.

! Heavy Editorial Imagery Slowdown: High-resolution lifestyle campaign shots created heavy page weight and slow mobile loading speeds.

! Missed Resortwear Cross-Sell Value: Customers purchased standalone swimsuits without discovering matching pareos, knit shorts, and cover-ups.

! Seasonal Traffic Surges: High-volume summer launch spikes required an ultra-fast, frictionless 1-click mobile checkout experience.
