Sometimes the simplest basics take the absolute longest to perfect because there's nowhere to hide the details. This is that perfect lightweight rib tee to layer up for early Fall 환절기 (that awkward transitional season). It’s fitted without suffocating you, and that asymmetric gorum tie is the ultimate subtle heritage flex.

Fit Tip: Fitted and cropped in femme proportions. Women should take their true size. Men should size up one.

⚖️ Risk of Loss (UCC § 2-509 — in human words):

Once we hand your package to USPS/UPS/FedEx and they scan it in, they are responsible for getting it to you.

We’re a small brand — we can’t absorb carrier mistakes the way Amazon can.

If you want coverage until final delivery, please add shipping protection at checkout.

Please note that Sundae School will not be liable for any lost/stolen shipments that do not have a shipping protection.

If you purchased package protection with your order and your package is lost, you can file a claim here.

Claims must be submitted no later than 30 days from the time of delivery. This is determined by the carrier, and is out of our control once outside the window.

⏰ FTC SHIPPING TIMING (16 CFR § 435)

We legally must ship within the time advertised — or within 30 days if nothing is stated.

If there’s a delay, we’ll notify you + give you the option to cancel for a full refund.

📦 PACKAGE PROTECTION

Your package protection covers shipping mishaps caused by carriers during transit. It is added to all orders by default, but you may remove it on the cart page before checkout. Please note that once it is removed, we're unable to assist with any shipping-related issues.

Your package protection also includes a free return label, meaning the cost of the return shipping is covered if you choose to return or exchange your order. However, it does not cover restocking fees charged by our third-party warehouse, as these are not related to shipping mishaps, nor overrides final-sale eligibility.

If your package is lost and you purchased Package Protection with your order, please file a lost package claim here.

🕵️ MISSING OR STOLEN PACKAGES

Once a package is marked “Delivered”, our delivery obligation is complete under UCC § 2-509 & § 2-510.

If it says “Delivered” but you can’t find it:

Check with neighbors/building staff
Contact the carrier to file a claim
We’ll support with any proof they need

We cannot refund, replace, or reship delivered packages.

Lost Before Delivery:

If tracking stalls or there’s no delivery scan, please contact the carrier for a “lost package” investigation.

We’ll help with documentation.

Undeliverable Packages:

Wrong address / refused / unclaimed → you cover re-shipping.

Original shipping isn’t refundable.

💸 DAMAGED / DEFECTIVE ITEMS

First of all, we’re so sorry that your item arrived in less-than-perfect condition 😭. While we don’t currently offer repair services, we’ll do our best to make this right for you.

Please email us at counselor@sundae.school with clear photos or videos of the issue, and our team will assist you as soon as possible.

Need an extra button?

Most of our garments include extra buttons inside the item. If your item did not come with extra buttons, feel free to reach out to us and we'll be happy to help.

Lost the extra buttons or your order was delivered over a month ago? You can still request replacement buttons for a small shipping fee.

💸 PRICE MATCHING

We’ll match a lower price with store credit within 7 days of purchase if:

The item is identical (size/color)
In stock
Sold full-price at sundae.school or an authorized retailer
You provide proof (screenshot/link)

Not eligible:

Flash sales, discount codes, bundles, promos, unauthorized resellers.

Adjustments:

Issued as store credit only, per UCC § 2-209 (contract modifications require written agreement).

Once store credit is issued, the transaction becomes final sale.

We currently ship to U.S. and Canada only. All international orders are final sale.

If you wish to have your orders delivered to outside the U.S. and Canada, we recommend forwarders like Forward2Me.
