General Questions

We source our clothes internationally from a variety of suppliers.

At the moment, we do not have a size guide as our clothes are sourced from different suppliers and may differ in sizing. Do refer to the measurements under our product listings for individual sizing references.

We do not have a physical store as of now. However, we do hold pop-up stores once in awhile. Follow our Instagram for first dibs when we have an upcoming one.

Student Discount

Yes we do! All students and fresh graduates in Singapore are entitled to 15% off your orders when you verify your student status with us here.

Once verification is complete, we will send you an email with your discount code. This code is unique to you and can be applied before every checkout.

We review applications on a first come first serve basis. We take pride in the confidentiality of your information and will require up to 1 working day to process your application.

We will let you know via email if you’ve been successfully verified or if additional information is required to complete your verification. Please check your spam/junk folder if you do not see an email in your inbox.

Our student discount is valid for all students and fresh graduates, your discount code will expire on the year of graduation. (E.g If you applied on 2 March 2020, and expect to graduate in 2023 the expiry will be on 1 March 2023)

You may check your student discount code and expiry date anytime when you login to your Three One Duo account.
