Ladies and Gentlemen:

We have acted as counsel to Atlantic International Corp., a Delaware corporation (the “Company”), in connection with the preparation of the Company’s registration statement on Form S-4, Registration No. 333-284049 (the “Registration Statement”), under the Securities Act of 1933, as amended (the “Securities Act”) by Amendment No. 1 filed by the Company with the Securities and Exchange Commission (the “Commission”) on this date, as thereafter amended or supplemented. The Registration Statement relates to the registration of the issuance (the “Offering”) by the Company of up to 2,108,188 shares (the “Offered Shares”) of common stock, $0.00001 par value, (the “Common Stock”), to be issued to the Staffing 360 Solutions Inc. (“Staffing 360”) shareholders, pursuant to the terms and conditions of the Agreement and Plan of Merger (the “Merger”) dated as of November 1, 2024, as amended, by and among the Company, A36 Merger Sub, Inc and Staffing 360 on January 7, 2025 (the “Merger Agreement”). The Offered Shares consist of: (i) 1,975,773 shares of Common Stock to be issued to Staffing 360 stockholders, (ii) 116,264 shares of Common Stock issuable upon exercise of outstanding warrants (the “Staffing 360 Warrants” and such shares, the “Warrant Shares”) to purchase common stock of Staffing 360 to be exchanged for warrants of Atlantic (the “Atlantic Warrants”), (iii) 6,151 shares of Common Stock issuable upon exercise of outstanding options (the “Staffing 360 Options” and such shares, the “Option Shares”) to purchase Common Stock of Staffing 360 to be exchanged for options of Atlantic (the “Atlantic Options”), and (iv) 10,000 shares that may be issuable as a result of the provision of the Merger Agreement that rounds up to the nearest share in lieu of issuing fractional shares.

In rendering the opinion set forth herein, we have examined the originals, or photostatic or certified copies, of (i) the Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) and the Amended and Restated Bylaws of the Company, each as amended to date and as filed as exhibits to the Registration Statement, (ii) certain resolutions of the Board of Directors of the Company related to the filing of the Registration Statement, the authorization and issuance of the Offered Shares and related matters, (iii) the Registration Statement and all exhibits thereto, (iv) the Merger Agreement; as amended and (v) such other records, documents and instruments as we deemed relevant and necessary for purposes of the opinion stated herein.

In making the foregoing 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 photostatic or certified copies, and the authenticity of the originals of such copies. As to all questions of fact material to this opinion, where such facts have not been independently established, we have relied, to the extent we have deemed reasonably appropriate, upon representations or certificates of officers of the Company or governmental officials.

Our opinions expressed herein are subject to the following qualifications and exceptions: (i) the effect of bankruptcy, insolvency, reorganization, arrangement, moratorium, or other similar laws relating to or affecting the rights of creditors generally, including, without limitation, laws relating to fraudulent transfers or conveyances, preferences, and equitable subordination; (ii) the effect of general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing (regardless of whether considered in a proceeding in equity or at law); and (iii) the remedy of specific performance and injunctive and other forms of equitable relief may be subject to the equitable defenses and to the discretion of the court before which any proceeding therefor may be brought. We express no opinion as to the enforceability of any indemnification or contribution provision, choice of law provision or as to the enforceability of any provision that may be deemed to constitute liquidated damages.

This opinion is limited in all respects to the General Corporation Law of the State of Delaware and we express no opinion as to the laws, statutes, rules or regulations of any other jurisdictions. The reference and limitation to the “General Corporation Law of the State of Delaware” includes all applicable Delaware statutory provisions of law and reported judicial decisions interpreting these laws. Our opinion is based on these laws as in effect on the date hereof. We express no opinion to the extent that any other laws are applicable to the subject matter hereof and express no opinion and provide no assurance as to compliance with any federal or state securities law, rule or regulation. Where our opinions expressed herein refer to events to occur at a future date, we have assumed that there will have been no changes in the relevant law or facts between the date hereof and such future date. Our opinions expressed herein are limited to the matters expressly stated herein and no opinion is implied or may be inferred beyond the matters expressly stated. Not in limitation of the foregoing, we are not rendering any opinion as to the compliance with any other federal or state law, rule or regulation relating to securities, or to the sale or issuance thereof.

In connection with this opinion, we have assumed that the Registration Statement, and any amendments thereto will have become effective, and the Common Stock will be sold in the manner described in the Registration Statement and the Prospectus relating thereto.

Based upon the foregoing, and subject to the qualifications, assumptions and limitations stated herein, we are of the opinion that:

The Common Stock to be issued by the Company has been duly authorized for issuance and, when issued under the terms and conditions of the Merger Agreement, will be validly issued, fully paid and non-assessable shares of Common Stock of the Company.

The Warrant Shares to be issued by the Company upon exercise of certain Staffing 360 Warrants to be assumed by Atlantic to become Atlantic Warrants, have been duly validly authorized and reserved for issuance and, when issued in accordance with the terms of the Atlantic Warrants and the respective Warrant Certificate, will be validly issued, fully paid and non-assessable.

The Option Shares to be issued by the Company upon exercise of certain Staffing 360 Options to be assumed by Atlantic to become Atlantic Options, have been duly validly authorized and reserved for issuance and, when issued in accordance with the terms of the Atlantic Options and the respective Option Certificate, will be validly issued, fully paid and non-assessable.

We hereby consent to the filing of this opinion with the Commission as an exhibit to the Registration Statement. We further consent to the reference to our firm under the caption “Legal Matters” in the prospectus constituting a part of the Registration Statement. In giving this consent, we are not admitting that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission. This opinion is given as of the date hereof and we assume no obligation to update or supplement such opinion after the date hereof to reflect any facts or circumstances that may thereafter come to our attention or any changes that may thereafter occur.

	Very truly yours,
