When you're shopping online, save a few things before you check out:

• The product description, especially the fiber content and care instructions.
• The product photos, particularly any showing the label close-up.
• The seller's name and listing date.

The reason? If the item arrives and the label doesn't match the listing, you have proof of what was advertised. That's useful if you need to file a complaint or ask for a return. Also, screenshot the care instructions—they might not be printed on the garment itself, or they might be hard to read after a few washes.

If you're in a physical store, snap a photo of the label before you buy. It's a quick way to remember what you got, and it helps you compare with other items later.
