Ladies and Gentlemen:

We have acted as counsel to The Estée Lauder Companies Inc., a Delaware corporation (the “Company”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of the Company’s Registration Statement on Form S-3 (the “Registration Statement”) under the Securities Act of 1933, as amended (the “Securities Act”) relating to the offering and sale by the stockholders of the Company named in the prospectus included in the Registration Statement (the “Selling Stockholders”) from time to time of up to 11,301,323 shares of Class A Common Stock, par value $.01 per share, of the Company (the “Class A Shares”), of which 11,034,685 Class A Shares will be issued upon conversion of 11,034,685 shares of Class B Common Stock, par value $.01 per share, of the Company (the “Class B Shares”) on the date hereof.

In so acting, we have examined originals or copies (certified or otherwise identified to our satisfaction) of (i) the Restated Certificate of Incorporation, as amended, of the Company, incorporated by reference as Exhibits 3.1 and 3.1a to the Registration Statement; (ii) the Amended and Restated Bylaws of the Company, incorporated by reference as Exhibit 3.3 to the Registration Statement; (iii) the Registration Statement, including the prospectus dated the date hereof contained within the Registration Statement; and (iv) such corporate records, agreements, documents and other instruments, and such certificates or comparable documents of public officials and of officers and representatives of the Company, and have made such inquiries of such officers and representatives, as we have deemed relevant and necessary as a basis for the opinion hereinafter set forth.

In such examination, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, conformed or photostatic copies, and the authenticity of the originals of such latter documents. As to all questions of fact material to this opinion that have not been independently established, we have relied upon certificates or comparable documents of officers and representatives of the Company.
