Zalando is the best at this: it shows guides by brand and flags when an item tends to run large or small based on other shoppers' returns. On SHEIN it pays to read the comments, where people say whether the sizing is true.

Zalando, with a hundred days to return and no cost, has the most generous policy in the sector and is the reason many people order three sizes and send two back.

The usual advice: check the ratings, ask for extra photos if there are only a few, ask for exact measurements, and never close the deal outside the platform, because that's where you lose all protection.

Platforms like SHEIN release thousands of new items a day at very low prices, and that model rests on very high resource use, short-lived garments and production conditions that have been the subject of repeated investigations and criticism. It's relevant information when deciding, though the purchase is everyone's own call.
