Use the retailer's own chart and the specific garment measurements where available. Conversion labels are starting points and may differ between brands and categories.

## A practical way to check

Find the chart linked to the actual item and compare relevant dimensions with clothing you own. Keep the original size label when asking the seller a question.

## What can lead you astray?

A generic conversion table can look precise without describing this garment. Do not assume a familiar label means a familiar cut or amount of ease.

## Put the answer in context

Separate information the listing provides from assumptions made from a photograph. Save the relevant product details while comparing options, and read current seller policies before paying. nista can provide a visual preview on supported pages; it does not verify a seller or measure physical fit.

## Frequently asked questions

### Can a virtual try-on replace the size chart?

No. A generated preview can help you explore an appearance but does not measure your body, garment dimensions or physical comfort.

### Where should I check current delivery and return terms?

Use the seller’s current product page, checkout and policy pages. Terms may depend on location, seller and the specific item.

### What is a useful first step for this question?

Find the chart linked to the actual item and compare relevant dimensions with clothing you own. Keep the original size label when asking the seller a question.
