Washing new clothes before wearing them is generally a good idea, and many people find it necessary for several reasons:
Remove chemicals and dyes: New clothes often contain chemicals and dyes from the manufacturing process. Washing them helps to remove these substances, which may cause skin irritation or allergies in some individuals.
Eliminate germs and bacteria: During the manufacturing, transportation, and storage processes, new clothes can come into contact with various surfaces and people. Washing them helps eliminate any germs or bacteria that might be present.
Get rid of residue: New clothes may have residues from sizing, starch, or other substances used to enhance their appearance or texture. Washing removes these residues and makes the clothes softer and more comfortable to wear.
Improve smell and freshness: Some new clothes may have a distinct "new" smell, which some people find unpleasant. Washing the clothes helps to improve their smell and freshness.
Ensure a better fit: Sometimes, clothes can shrink or change shape slightly after the first wash. Washing them before wearing ensures that you get the correct fit and prevents disappointment if the clothes no longer fit well after the first wash.
However, there is no strict rule, and some people may choose to wear new clothes without washing them first. If you decide not to wash new clothes before wearing them, you can consider hanging them outside or in a well-ventilated area for a while to allow any odors or chemical residues to dissipate before putting them on. Ultimately, it comes down to personal preference and any specific concerns you may have about the new clothes.
