Tokyo Soir Co., Ltd. (Headquarters: Chuo-ku, Tokyo; President: Junichi Koizumi), a developer of women's formal wear, has released a suit for mothers designed for elementary school entrance exam scenes—including school information sessions, campus tours, application submissions, and interviews—under the supervision of Rieikai (Headquarters: Yokohama, Kanagawa; President: Masato Yoneda), an elementary school entrance exam cram school operated by Rikyu Co., Ltd.

Amidst a declining birthrate, interest in educational investment per child remains high, and families opting for private elementary schools have remained steady. The elementary school entrance exam season is long, running from April to November, and due to record-breaking heat in recent years, parents have increasingly voiced needs for clothing that looks proper even in the heat and can be worn across various occasions from information sessions to interviews.

This new product was developed combining Tokyo Soir's expertise in formal wear with Rieikai's proven track record in entrance exam guidance. It features the cleanliness, reliability, and elegance required in exam settings, while also being comfortable for long periods and designed for versatility.

[Supervision Points by Rieikai] - Two-piece style dress: Looks polished even as a single piece. - Stretch material: Easy to move in for long information sessions or travel; does not feel constricting. - Wrinkle resistance: Maintains a beautiful impression even after sitting. - 110cm length design: Covers the knees even when seated for an elegant look. - Washable: Can be easily washed at home to keep clean. - Triacetate/polyester material: Lightweight, easy to wear year-round, and comfortable during hot seasons. - Front-opening zipper: Easy to put on and take off, preserving hair and makeup. - Pockets: Smart storage for items like handkerchiefs.

In addition, a water-repellent sub-bag that fits A4 size and can be worn over the shoulder will also be available.
