2,000,000 Shares of Common Stock

Ladies and Gentlemen:

We have acted as counsel for Lulu’s Fashion Lounge Holdings, Inc., a Delaware corporation (the “Company”), in connection with the Registration Statement on Form S-8 (the “Registration Statement”) filed by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), relating to the registration of 2,000,000 shares of common stock, par value $0.001 per share (the “Shares”), issuable pursuant to the Company’s Omnibus Equity Plan, as amended (the “Omnibus Equity Plan”).

In that connection, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate records and other instruments as we have deemed necessary or appropriate for the purposes of this opinion, including: (a) the Fourth Amended and Restated Certificate of Incorporation of the Company, as amended through the date hereof; (b) the Second Amended and Restated Bylaws of the Company, as amended through the date hereof; (c) certain resolutions adopted by the Board of Directors of the Company; (d) the Omnibus Equity Plan; and (e) the Registration Statement and exhibits thereto.

This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Act. This opinion is limited to the matters expressly stated herein and no opinions are to be inferred or implied beyond the opinions expressly so stated.

With your permission, we have made and relied upon the following assumptions, without any investigations or inquiry by us, and our opinion expressed below is subject to, and limited and qualified by the effect of, such assumptions: (i) all corporate records furnished to us by the Company are accurate and complete; (ii) the Registration Statement filed by the Company with the Commission is identical to the forms of the documents that we have reviewed; (iii) all statements as to factual matters that are contained in the Registration Statement (including the exhibits to the Registration Statement) are accurate and complete; (iv) the Company will at all times reserve a sufficient number of shares of its unissued common stock as is necessary to provide for the issuance of the Shares; (v) the consideration, if any, required to be paid in connection with the issuance of Shares pursuant to the Omnibus Equity Plan is actually received by the Company as provided in the Omnibus Equity Plan; and (vi) with respect to documents that we reviewed in connection with this opinion, all documents submitted to us as originals are authentic, all documents submitted to us as certified, facsimile or photostatic copies conform to originals of such documents, all such original documents are authentic, the signatures on all documents are genuine, and all natural persons who have executed any of the documents have the legal capacity to do so.

Based on the foregoing and subject to the assumptions and qualifications set forth herein, we are of the opinion that the Shares have been duly and validly authorized, and when, and if, issued pursuant to the terms of the Omnibus Equity Plan will be validly issued, fully paid, and nonassessable shares of common stock of the Company.
