Despite entering September, the scorching summer heat in Korea shows no signs of easing — yet some fashion-forward stars are already defying seasonal norms. K-pop idols Giselle of aespa and Rosé of BLACKPINK have drawn attention for their unexpected choice of Ugg-style footwear in the middle of summer, raising speculation about whether a new trend is emerging.
Giselle recently shared a series of everyday photos on her social media, showcasing a casual yet stylish outfit. She paired a fitted black zip-up top with oversized Bermuda sweat shorts, finishing the look with a cap and sunglasses for a relaxed vibe. While the outfit could have appeared simple, one bold styling choice set it apart — Ugg-style boots.

Traditionally known as winter shoes made from sheepskin and lined with wool, these boots are rarely associated with summer fashion. However, Giselle’s pairing of cozy boots with a lightweight outfit gave her look a chic, edgy twist. The boots, priced at about 1 million won ($730), feature a denim-print finish on leather, adding a standout element to her otherwise minimal ensemble.
Giselle is not alone in embracing this seasonal twist. BLACKPINK’s Rosé also made headlines with her airport look, wearing Ugg-style slippers crafted from the same fluffy material used inside traditional Ugg boots. With their low heels and soft lining, the slippers combined comfort with a unique aesthetic, perfectly complementing Rosé’s effortless off-duty style.
As more K-pop stars experiment with sheepskin-style footwear despite the sweltering heat, all eyes are on whether this “midsummer Ugg” styling could spark the next big K-fashion trend.
