Order chapter-branded apparel:

ATSSA has coordinated with Corporate Casuals to pay the digitization for the national ATSSA and all chapter logos. They can be used on any customizable item you choose from their site. Order directly from Corporate Casuals and have your items delivered to you! ATSSA is unaffiliated with Corporate Casuals and does not receive any portion of revenue from sales with the ATSSA brand.

To access your chapter’s logo, begin by using this chapter-specific share link and create a free Corporate Casuals account. After doing so, the chapter logos will automatically be linked to your profile and can be added to apparel or accessories.

If you are unable to create a new account because you have an existing account with them, please reach out to our Corporate Casuals representative, Soheila Lopopolo (slopopolo@corporatecasuals.com), to request that the national and/or chapter logo(s) be added to your account at no additional fee.
