PROXY STATEMENT

General

The board of directors of LightInTheBox Holding Co., Ltd. (the “Company” or “we”) is soliciting proxies for the annual general meeting of shareholders of the Company to be held on June 29, 2016 at 10:00 a.m., local time (the “AGM”). The AGM will be held at ICBC Tower, 35/F, 3 Garden Road, Hong Kong.

This Proxy Statement and the proxy form can be accessed, free of charge, on the Investor Relations section of the Company’s website at http://ir.lightinthebox.com.

Revocability of Proxies

Any proxy given pursuant to this solicitation may be revoked by the shareholder (a) submitting a written notice of revocation or a fresh proxy form bearing a later date at least 48 hours before the time of the AGM; or (b) attending the AGM and voting in person.

Record Date, Share Ownership and Quorum

Only shareholders of record at the close of business on June 10, 2016, New York time (the “Record Date”) are entitled to attend and vote at the AGM. As of June 10, 2016, 137,514,017 of our ordinary shares, par value $0.000067 per share (“Ordinary Shares”) were outstanding. Approximately 46,941,782 Ordinary Shares were represented by American Depositary Shares (“ADSs”) held by The Bank of New York Mellon. Holders of record of the ADSs at the close of business on the Record Date who wish to exercise their voting rights for the underlying Ordinary Shares must act through The Bank of New York Mellon. Two shareholders holding not less than an aggregate of one-third in par value of the share capital of the Company in issue present in person or by proxy or, if a corporation or other non-natural person, by its duly authorized representative or proxy and entitled to vote shall be a quorum for all purposes.

Voting and Solicitation

Each Ordinary Share issued as of the Record Date is entitled to one vote on a poll. A resolution put to the vote at the AGM will be decided on by a show of hands unless (before or on the declaration of the result of the show of hands or on the withdrawal of any other demand for a poll) a poll is demanded by (i) the chairman of the AGM, or (ii) any one shareholder present in person or in the case of a shareholder being a corporation by its duly authorized representative or by proxy for the time being entitled to vote at the AGM.

Copies of solicitation materials will be furnished to all holders of Ordinary Shares of the Company, including banks, brokerage houses, fiduciaries and custodians holding in their names our Ordinary Shares or ADSs beneficially owned by others to forward to those beneficial owners.

Voting by Holders of Ordinary Shares

When proxies are properly dated, executed and returned by holders of record of the Ordinary Shares at the close of business on the Record Date, the Ordinary Shares they represent will be voted at the AGM, or at any adjournment thereof, in accordance with the instructions of the shareholder. If no specific instructions are given by such holders, the proxy holder will vote or abstain at his/ her discretion, as he/ she will on any other matters that may properly come before the AGM, or at any adjournment thereof. Abstentions by holders of record of the Ordinary Shares are not included in the determination of the number of Ordinary Shares present and voting.

Voting by Holders of ADSs

We have requested The Bank of New York Mellon, as depositary of the ADSs, to mail to all owners of record of the ADSs at the close of business on the Record Date this proxy statement, the accompanying notice of annual general meeting and an ADR Proxy Card. Upon the timely receipt from an owner of record of the ADSs of written voting instructions in the manner specified, The Bank of New York Mellon will endeavor, to the extent practicable and legally permissible, to vote or cause to be voted the number of Ordinary Shares represented by the ADSs, evidenced by American Depositary Receipts (“ADRs”) related to those ADSs, in accordance with such voting instructions. Under the terms of the deposit agreement, The Bank of New York Mellon will not vote or attempt to exercise the right to vote other than in accordance with such voting instructions or such deemed instructions as further described two paragraphs below.  As the holder of record for all the Ordinary Shares represented by the ADSs, only The Bank of New York Mellon may vote those Ordinary Shares at the AGM.

2

There is no guarantee that holders of record of the ADSs or any such holder in particular will receive the notice described above with sufficient time to enable such holder to return any voting instructions to The Bank of New York Mellon in a timely manner, in which case the Ordinary Shares underlying your ADSs may not be voted in accordance with your wishes.

If (i) the enclosed ADR Proxy Card is missing voting instructions, (ii) the enclosed ADR Proxy Card is improperly completed or (iii) no ADR Proxy Card is received by The Bank of New York Mellon from a holder of ADSs by 5:00 p.m. (New York City time), June 23, 2016, The Bank of New York Mellon will deem such holder of record of the ADSs to have instructed it to give a discretionary proxy to the chairman of the AGM to vote in favor of each proposal recommended by our board of directors and against each proposal opposed by our board of directors, unless the Company has informed The Bank of New York Mellon that such proxy should not be given, in accordance with the terms of the deposit agreement.
