THOUSAND MILE | LaLa Begin Exclusive UV Cut One-Piece Dress

THOUSAND MILE creates functional items that combine durability and comfort.
For 2025, we've created a LaLa Begin exclusive version of our popular one-piece dress.

This sleeveless one-piece dress will keep you comfortable on hot summer days. It's made from a multi-functional material that is lightweight, breathable, quick-drying, and UV-cut. The simple design, with a slightly reduced casual feel, is perfect for adult women.

3 Key Features
1. Uses new 2025 multi-functional material (lightweight, breathable, quick-drying, UV-cut, 2-way stretch, dry touch)
This material was developed inspired by the traditional Japanese heat-cooling method, 'sudare' (bamboo blinds). It features slit-like breathable sections and a 3D woven structure with gaps, creating a highly functional and comfortable polyester material that blocks UV rays while offering excellent breathability. It's the perfect material for Japan's hot and humid summer climate.
2. Thoughtful Design
We've focused on a simple design with a reduced casual feel and excellent comfort, suitable for adult women. The silhouette is close to an I-line that falls straight, but with slits on both sides for active movement. It looks great worn on its own or paired with leggings or pants.
The armholes are designed to make upper arms appear slimmer, prevent fabric from rubbing against the sides, and minimize the visibility of innerwear. (Individual fit may vary.)
Side pockets are included for storing small items like keys or a smartphone.
3. Machine Washable! Easy Care
Machine washable items are a must for summer wear, aren't they? This item is machine washable (home laundry safe) and quick-drying, so it dries quickly after washing!
