Use photos as a starting point
An image helps you understand the model's appearance, but it does not replace the written size, material or care information. Check the published product fields and ask when an important detail is missing.
Record the exact reference
Copy the product URL or code and the selected colour. Similar models can have different size runs or prices. A precise reference lets the sales advisor answer your question without guessing which garment you mean.
Read the price in its context
Check whether the displayed amount is per piece or for a complete series, how many pieces the series contains and which currency is shown. Multiply by the number of series you intend to request before comparing models.
Separate facts from open questions
For two dresses intended for different celebrations, you may need different information before ordering. Mark the unknowns on your shortlist. Availability, final totals and delivery conditions are confirmed for the actual request, not inferred from the catalogue.
