We report an evaluation benchmark for assessing the operational suitability of Vision-Language Models (VLMs) in fashion e-commerce. General-purpose benchmarks do not adequately cover fashion-specific attributes or the structured extraction tasks common in e-commerce workflows. We define five tasks across two image streams---outfit and single-item product images---and compare six commercial and two open-source models with multiple prompt variants, including a canonical prompt and model-proposed prompts. Experiments show that the best-performing model varies by task, error patterns are more model-dependent than prompt-dependent, and model updates can improve some tasks while degrading others. These results indicate that task-specific evaluation, prompt robustness checks, and continuous monitoring are practical requirements for deploying VLMs in production fashion systems.
