Amendment Description	Inter Parfums, Inc. (“Inter Parfums”) is filing this Amendment No. 1 on Form 10-K/A (“this Amendment”) solely to correct a typographical error on the date of signature of the Consent of Independent Registered Public Accounting Firm on Exhibit 23 as set forth in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019 (the “Original 10-K”). The Original 10-K was filed with the United States Securities and Exchange Commission (the “SEC”) on March 2, 2020. Although Inter Parfums had received the signed consent for Exhibit 23 with the correct date from its independent registered public accounting firm on March 2, 2020, an incorrect date was included in the Original 10-K filing with the SEC. This Amendment does not amend or otherwise update any other information in our Original 10-K. Accordingly, this Amendment should be read in conjunction with our Original 10-K and with our filings with the SEC subsequent to our Original 10-K.
