Exhibit 3.1

Certificate of Amendment
of
Amended and Restated Certificate of Incorporation
of
My Size, Inc.

Under Section 242 of the Delaware General Corporation Law

My Size, Inc., a corporation organized and existing under the laws of the State of Delaware (the “Corporation”) hereby certifies as follows:

FIRST: The Amended and Restated Certificate of Incorporation of the Corporation is hereby amended by replacing FIFTH ARTICLE in its entirety with the following:

FIFTH: The total number of shares of stock which the Corporation shall have authority to issue is 250,000,000 shares of common stock with a par value of $0.001 per share (the “Common Stock”). The Common Stock may be issued from time to time without action by the stockholders. The Common Stock may be issued for consideration as may be fixed by the Corporation’s Board of Directors (the “Board of Directors”).

The foregoing amendment shall be effective as of 4:30 p.m., New York City time on August 12, 2026 (the “Effective Time”), upon which every eight (8) shares of the Corporation’s Common Stock (the “Old Common Stock”), issued and outstanding immediately prior to the Effective Time, will be automatically reclassified as and converted into one (1) share of common stock, par value $0.001 per share, of the Corporation (the “New Common Stock”) (such formula herein, the “Determined Ratio”). Further, every right, option and warrant to acquire shares of Old Common Stock outstanding immediately prior to the Effective Time shall, as of the Effective Time and without any further action, automatically be reclassified into the right to acquire one (1) share of New Common Stock based on the Determined Ratio of shares of Old Common Stock to shares of New Common Stock, but otherwise upon the terms of such right, option or warrant (except that the exercise or purchase price of such right, option or warrant shall be proportionately adjusted).

Notwithstanding the immediately preceding paragraph, the Corporation shall not be required to issue or deliver any fractional shares of New Common Stock. At the Effective Time any such fractional interest in such shares of New Common Stock shall be converted into the right to receive, an amount in cash, without interest, determined by multiplying (i) the closing sale price of the Common Stock (on a post-reverse-split basis as adjusted for the amendment effected hereby) on the trading day immediately prior to the Effective Time as reported on the Nasdaq Capital Market, by (ii) such fractional share interest to which the holder would otherwise be entitled. Shares of Common Stock that were outstanding prior to the Effective Time and that are not outstanding after the Effective Time shall resume the status of authorized but unissued shares of Common Stock.

Each stock certificate that, immediately prior to the Effective Time, represented shares of Old Common Stock shall, from and after the Effective Time, represent that number of whole shares of New Common Stock into which the shares of Old Common Stock represented by such certificate shall have been reclassified (as well as the right to receive cash in lieu of any fractional shares of New Common Stock as set forth above); provided, however, that each holder of record of a certificate that represented shares of Old Common Stock shall receive, upon surrender of such certificate, a new certificate representing the number of whole shares of New Common Stock into which the shares of Old Common Stock represented by such certificate shall have been reclassified, as well as any cash in lieu of fractional shares of New Common Stock to which such holder may be entitled pursuant to the immediately preceding paragraph.

SECOND: The foregoing amendment has been duly adopted in accordance with the provisions of Section 242 of the General Corporation law of the State of Delaware and has been duly approved by the stockholders of the Corporation.

THIRD: This Certificate of Amendment shall be effective at 4:30 p.m. Eastern Time on August 12, 2026.

IN WITNESS WHEREOF, I have signed this Certificate this 12^th day of August, 2026.
