We’ve seen some crazy things from Japan, but this is the first time we’ve ever seen a blanket dressed up as a school uniform.
Bibi Lab, the Japanese retailer known for bringing out crazy items like the Cotton Wife, the rolling umbrella and the twintails pillow, has been making news recently for their Sera Kore (“Sailor Collection”) line of uniform-style sweat suits. Bibi Lab first ventured into the realm of sailor-style roomwear for the home with a fleecy men’s version released last year. Following its huge success, the company released a lineup of Sera Kore spring and winter designs, and now as we get into the depths of winter, they’ve come up with an even cosier solution to keep the indoor school uniform trend alive until spring.
▼ Say hello to the “Sera Kore Wearable Blanket Type Sailor Uniform Pyjamas”.
Now that we’re all used to the idea of a fleecy school uniform, thanks to Bibi Lab’s previous roomwear collections, the company is now giving us a wearable blanket that looks like a sailor uniform. Despite the “pyjama” classification, this roomy outfit is designed to keep the wearer warm while lounging around at home.
The long, flared skirt style makes it easy to walk around the house, and even twirl around in like a schoolgirl if you want to, but the design really comes into its own when worn in a seated position.
According to the makers, this is when it becomes a “Self Kotatsu”, meaning it traps heat around the legs in the same way as a kotatsu, which is a low, blanketed table equipped with a heater underneath.
And because the outfit doubles as pyjamas, you won’t have to worry about getting changed and exposing your skin to the cold before bedtime. Although it might feel strange at first to drift off to sleep while wearing a Japanese-style uniform.
▼ We wonder if Japanese schoolgirls wish they could wear this at school instead of their own uniforms, to help cope with those freezing classrooms.
The thick fleece material extends to the sailor-style collar, which means people around you can use the outfit to keep their hands warm too!
The wearable blanket is currently available to purchase from online retailers like Amazon Japan, Rakuten and Village Vanguard, where it’s sold in one size and has a recommended retail price of 9,720 yen (US$85.66). With so many weird yet wonderful features, we’re sure this is going to be another popular hit for the Bibi Lab team!
