The Story Behind the Dress

Designer's Note


“A Dress That Spreads a Little Joy”


I wanted to create a dress that could be enjoyed casually in everyday summer life. That idea became this T-shirt dress.

The waist is shaped with twelve tucks, a detail I often use in my designs. The fabric is the same one I have trusted for years in my classic T-shirts. It holds its shape well even after frequent wear, which is one of the reasons I keep coming back to it.

For me, the purpose of making clothes is to create joy through what I make.

First, I create something that I genuinely find beautiful. Then someone wears it, feels a little happier, smiles, or simply enjoys their day a little more. And sometimes, that happiness spreads to the people around them too.

Each of those moments may be small, but I like to think that if they keep spreading little by little, the world might become just a little more beautiful.

It may sound like a big idea, but that is something I keep in mind as I continue making dresses every day.
