Wacky WiLLy summer pop-up in Gangnam — limited merch and Giselle pieces

Wacky WiLLy, the Korean streetwear brand that dresses Aespa's Giselle, just opened a summer pop-up in Gangnam — and if you're planning a Seoul trip, this is worth timing around. The brand fuses fashion, street culture, and art into witty, colorful pieces that lean romantic and playful rather than minimal, which means the pop-up itself feels tactile and gallery-like rather than sterile.

The pop-up runs June 11–24, 2025 at Shinsegae Gangnam (8th floor Bridge area), which is easy to reach and walk into without booking — just show up during store hours (10:30 AM–8 PM daily). The space showcases the full summer collection: oversized hoodies with graphic typography, mini skirts with balloon silhouettes and lily artwork, ruffled tees, square-neck cotton blouses with puff sleeves, and check-pattern sets. Giselle's signature pieces — the heart-ruffle short-sleeve tee and balloon-ribbon mini skirt — are in stock, so if you've seen her wear something and want to try it on, you can.

Limited-time pricing hits hard: basic baseball cap for 10,000 won, logo tee for 20,000 won, basic shorts for 30,000 won (10 pieces weekdays, 30 weekends). There's also stacked discounts on multi-buys — 10–30% off the full range, plus an extra 10% if you grab 2+ pieces or 15% for 3+. The 2-pack tee bundle drops from 49,000 to 29,000 won.

Spend 70,000 won or more and you get a pull from the in-store claw-machine game for free branded goods (keychains, socks, accessories). The blogger walked away with socks, and honestly, the machine itself is a photo moment — it's designed to catch your eye.

Wacky WiLLy's whole thing is bold color blocking, playful embroidery, and silhouettes that feel fresh without trying too hard. The check patterns are navy and soft blue (summer-ready), the graphics lean into cute-meets-cool, and pieces layer well — a single tee works with multiple skirts, blouses pair with denim, and the reversible leopard tote is roomy enough for a day out. If you're after something with personality that photographs well and doesn't scream "tourist brand," this is it.

Cluster this pop-up with other Gangnam stops on your Seoul itinerary — the location is central enough that you can hit it between café runs or shopping in the neighborhood.
