Introducing the CHARCOAL DOUBLE DUTY BLAZER by Sundae School—a refined wool blend blazer in deep charcoal, featuring notched lapels, front button closure, a chest pocket, and a fabric belt elegantly tied at the waist. Inspired by the silhouette of a hanbok, this design is finished with subtle button accents near the cuffs for an elevated touch.

The CHARCOAL DOUBLE DUTY BLAZER by Sundae School is showcased laid flat on a white background, captured from the upper chest to the collar. The open jacket reveals its smooth, dark inner lining—an indication of meticulous craftsmanship. With no buttons or accessories visible, its clean lines and minimalist aesthetic evoke the modern hanbok silhouette. Crafted from a premium wool blend in dark gray charcoal.

This is the piece we are most proud of, no cap. We spent a literal year obsessing over this construction because it represents the ultimate existential crisis—feeling Korean, American, both, and sometimes neither, all in one day. The entire goal was pure, high-end optionality.

We finally unlocked premium territory here. First 50% wool blend. We would’ve gone 100%, but let’s be honest: you’re not trying to pay that price tag (don't lie!). This is also our first blazer with proper shoulder pads, because structure doesn’t have to sacrifice comfort.

But here’s where it gets special: there's a hidden mechanism for the goreum ties on both sides. Keep it standard for that clean, semi-double tailored look. But when you’re feeling super connected to the culture—or just want that snatched waist silhouette—whip the ties out and cinch. However you’re showing up that day, this blazer keeps up.

⚖️ 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.
