How can I check whether secondhand clothes were altered?

Ask directly and inspect seams, hems, straps and labels where photographs allow. Current measurements are useful even when the seller does not know the alteration history.

A practical way to check

Request interior photos and compare the dimensions with the expected construction. Ask a tailor about feasibility if reversing a change is important.

What can lead you astray?

A different stitch line may suggest a change but is not conclusive by itself. Do not assume every alteration can be undone.

Put the answer in context

Ask about this specific item rather than relying on the brand’s original description. Previous wear, repairs and alterations can change its dimensions and condition. Keep the seller’s written answers and use the marketplace’s supported payment and communication routes.

Read the related guide for the broader decision. If you use a generated clothing preview, compare it with the original product photo and read what a preview can establish.
