Final answer:
YSL's signed letter confirming an oral agreement for the sale of gowns satisfies the Statute of Frauds (SOF) against Macy's since they did not object within the UCC's 10-day period, making the contract enforceable.
Step-by-step explanation:
The question refers to the Statute of Frauds (SOF), which is a legal principle that requires certain types of contracts to be in writing to be legally enforceable. Specifically, it pertains to contracts for the sale of goods over a certain amount of money (which varies by jurisdiction but is often $500 or more). In this scenario, YSL's signed letter confirming an oral agreement for the sale of 9 gowns to Macy's for $2,700 implies a contract that falls within the purview of the SOF due to the dollar value involved.
Under the Uniform Commercial Code (UCC) which governs commercial transactions in the United States, a written confirmation between merchants, which is sufficient against the sender, can satisfy the SOF and bind the recipient if the recipient does not provide a written notice of objection within 10 days. Since Macy's did not respond to YSL's confirmation letter, the SOF is considered satisfied with this contract according to the UCC. Therefore, YSL's signed confirmation letter would indeed satisfy the SOF against Macy's, making the agreement enforceable.
