This Musinsa Seongsu open-run review is based on the confirmed opening-weekend figures and event details released around Musinsa Megastore Seongsu. The key takeaway is practical: the April 24-26, 2026 opening rush was driven by early queues, first-come benefits, large-scale fashion and beauty shopping, and event-linked demand rather than a simple store-opening curiosity.1
Musinsa Megastore Seongsu officially opened in Seoul’s Seongsu-dong on April 24, 2026, as a major offline fashion and beauty store. Over its first three days, from April 24 to 26, the store recorded about 42,000 visitors and roughly 900 million won in transactions, with April 25 alone exceeding 300 million won in sales.1
Musinsa Seongsu Open-Run Review: What Happened During the Rush

The opening weekend was crowded from the start. Musinsa reported that waiting lines formed in front of the store from early morning, and about 26,000 products were sold during the three-day opening period.1 For readers trying to understand whether the open-run was mainly about browsing, the figures point to a shopping-heavy launch: visitors were not only entering the store, but also buying in significant volume.
The same opening-weekend data shows why the rush became a notable Seongsu retail event. More than 52% of purchasers were in their teens and twenties, while foreign customers accounted for about 23% of buyers.1 That mix helps explain the visible demand: Musinsa Seongsu drew younger domestic shoppers, beauty and fashion customers, and overseas visitors at the same time.
Financial News also reported Musinsa’s opening figures, including 42,000 visitors and 900 million won in transactions within three days. The report added that long lines continued through the weekend and that the average transaction amount per customer was in the 100,000-won range.2 For a practical open-run assessment, that average spend matters because it suggests many visitors treated the launch as a purchase opportunity, not only as a photo stop or landmark visit.
The highest-pressure period was tied to specific opening benefits. Musinsa had announced first-come, first-served “Mega Bag” sales for April 24, and first-come discount coupons of up to 50,000 won for customers spending 100,000 won or more on April 25 and 26.3 Those exact opening benefits have already ended, so visitors planning after the opening weekend should not expect the same first-come promotions.
What Visitors Could Do Inside Musinsa Megastore Seongsu
Musinsa positioned Musinsa Megastore Seongsu as Korea’s largest offline fashion and beauty store by single-store standard when it opened on April 24.3 Seoul Shinmun reported the store at 2,000 pyeong, or about 6,612 square meters, and described it as twice the size of the Yongsan megastore, with nearly four times as many participating brands.4
That scale matters for visitors because the store is not limited to one shopping category. The second floor includes Musinsa Beauty’s first offline store, with more than 700 brands.4 For beauty shoppers, this makes the Seongsu location a physical testing and browsing point connected to a platform that many customers already use online.
Other floors also shaped the opening-weekend appeal. Seoul Shinmun reported that the basement first floor includes “Musing-sa,” while the fourth floor includes “Food Garden.”4 The store also introduced O4O functions that let shoppers scan product QR codes to check real-time prices, customer reviews, and styling tips.4 In a crowded open-run setting, that kind of product information can help visitors compare items quickly without relying only on in-store displays.
For anyone using the opening rush as a guide to a later visit, the practical lesson is to separate expired launch benefits from ongoing store features. The opening weekend’s first-come promotions and early queues were time-specific. The store layout, beauty floor, QR-based product information, and large brand mix remain the more relevant reasons to visit after the launch period.
May 2026 Visit Notes and Timing
After the opening weekend, May visits are tied to separate beauty and collaboration events, each with its own schedule. Musinsa Beauty Festa runs from May 4 to 14, 2026, with about 540 beauty brands and roughly 12,000 products participating; Musinsa said the event can also be experienced at Musinsa Megastore Seongsu, where offline-only instant discount benefits are provided depending on payment amount.5
A separate Witchy collaboration with Tomorrow X Together’s official character Ppulbatu is running as an offline pop-up at Musinsa Megastore Seongsu from May 5 to 24, 2026. Participation programs including a stamp event and lucky draw run through May 18, and Musinsa said additional product quantities would be added from May 8 after some collaboration items sold out soon after release.6
That means visitors should check the exact event window before going. For example, Beauty Festa is only relevant through May 14, while the Witchy x Ppulbatu pop-up continues through May 24, with some participation programs ending earlier on May 18.56 The dates are not interchangeable, so the best visit timing depends on whether the goal is beauty discounts, the collaboration pop-up, or simply exploring the megastore.

Quick FAQ
Is the Musinsa Seongsu opening-weekend open run still happening?
No. The opening weekend covered April 24-26, 2026, and the first-come launch benefits announced for those dates have passed.3 Later visitors should look at current store events rather than planning around the original opening promotions.
What should visitors focus on after the opening weekend?
The most useful confirmed points are the large fashion and beauty store format, the Musinsa Beauty offline floor, QR-based product information, and the May event schedules. Beauty Festa runs through May 14, while the Witchy x Ppulbatu pop-up runs through May 24 with some programs ending May 18.456 For a practical Musinsa Seongsu open-run review, the opening weekend showed strong demand, early queues, and heavy purchasing, while later visits should be planned around the store’s permanent shopping features and the precise end dates of active May events.
