Shechiyanu for new items

Buying items of importance

1. If one builds a new house or buys or receives a new vessel or clothing of significance a Shechiyanu is required.
2. Getting new clothing which aren’t significant such as undershirts, sweaters, white-shirts, pajamas, and socks, no Bracha is required.
3. In general, shoes don’t require a Bracha of Shechiyanu, however, expensive and important shoes can require a Bracha unless they are made from leather in which case there’s a dispute if the Bracha should be made.
4. Important clothing such as a suit, tuxedo, expensive hat, or shtriemel can deserve a Shechiyanu if the clothing brings joy to a person. Some have the minhag not to make Shechiyanu on clothing at all.
5. There’s a dispute whether one can make a Bracha for buying new Seforim, however, if one receives important Seforim as a present one can make a Shechiyanu.

If it benefits others

1. If the new house, vessel, or clothing also benefit others with a physical benefit, then one should make HaTov VeHaMeitiv, however, if it’s only beneficial to oneself, make Shechiyanu.
2. For buying a new and significant household item (such as air-conditioning or cabinets) the minhag is not to make a HaTov VeHaMeitiv, however, the one who makes the Bracha has nothing to loss.
3. One should make a Shechiyanu upon buying a new car unless one's family will also use it in which case one should make HaTov VeHaMeitiv.

When to make Shechiyanu

1. The halacha is that the Bracha should be made at the time of buying the new clothing, however, the minhag is to make the Bracha when wearing the clothing.
