する【する (Have / Wear)】

Beyond its basic meaning of "to do," する has several important extended usages that cover wearing, sensing, costing, and deciding. These are essential to natural Japanese and appear frequently in everyday conversation.

Wearing accessories: ～をする

Sensing: ～がする

When describing sensations such as smells, sounds, tastes, or feelings, Japanese uses the pattern ～がする. The subject is the sensation itself, marked with が.

Costing: ～する

Deciding on: ～にする

The pattern ～にする means "to decide on" or "to go with" something. It is very common when ordering at restaurants or making choices.

Making into: ～にする
