Korea has a substantial cosplay and costume production scene serving domestic conventions, with construction quality that sits between cheap mass-market costumes and expensive commissions. The catch is that most of it is made to order, which changes how you have to plan around a convention date.
Where the goods actually are
Korean online marketplaces and independent maker shops carry costume sets, wigs, props and accessories. Full costume sets typically run 60,000 to 250,000 KRW depending on complexity. Independent makers often sell through social accounts and take orders by message rather than through a storefront, which is where the language barrier bites hardest. Prices from independent makers are usually quoted per piece rather than per set, so a listing that looks cheap may cover only the jacket rather than the full costume.
Made to order means five to fifteen business days
Most costume pieces are produced after the order is placed. Add that to consolidation and international transit and a realistic total is four to seven weeks from ordering to having the costume in hand. For a convention date, ordering ten weeks out is comfortable and six weeks is tight. Peak convention season in Korea, roughly July through September, extends production times by another week or two because makers are working through a queue.
Sizing is the biggest risk
Korean costume sizing runs small and is usually given as chest, waist, shoulder and length measurements rather than S, M, L. Measure yourself in centimeters and compare against the chart rather than converting from a US size. Many makers offer custom measurements for a surcharge of roughly 15,000 to 40,000 KRW, which is far cheaper than an unusable costume.
Props and the shipping problem
Long props, armor pieces and anything rigid are volumetric nightmares and occasionally prohibited outright, particularly replica weapons. A 90 cm prop sword may bill as 6 to 8 kg of volumetric weight regardless of its actual mass. Prop items that disassemble are worth paying more for, and anything resembling a weapon needs to be checked against import rules before ordering.

Are replica weapons shippable?
It depends heavily on material, appearance and the specific item. Foam and clearly non-functional props are usually fine, metal replicas frequently are not. Check before buying rather than after.
Can I return a costume that does not fit?
Made-to-order items are typically non-returnable, and international return shipping usually exceeds the item value anyway. Measurements are the whole game in this category.
Do Korean makers work with English?
Some do, many communicate only in Korean and by messenger app. Orders placed through an intermediary who can handle the measurement conversation are noticeably less error-prone.
