FANTASTICDAYS
A brand dedicated to creating pants that fit evolving lifestyles in a changing world. Combining practicality suited for different climates and occasions with refined design, FANTASTICDAYS aims to deliver trousers that make you feel like a new version of yourself simply by wearing them. Built on the concept of “DRESS UP & RELAX,” the brand continues to propose modern, functional pieces that support a positive and sophisticated everyday life.


Lightweight Polyester Linen with a Natural Texture
The fabric is composed of 95% polyester and 5% linen. While easy to handle and lightweight, it still carries the subtle slub texture and breezy feel typical of linen.
Designed with a thin, spring–summer fabric, it feels lighter than it appears. The front is lined, ensuring a comfortable touch against the skin even with the wide silhouette.
The result is a material that feels cool and breathable without appearing overly casual—perfectly balanced for refined everyday wear.
Easy Comfort with the Look of Slacks
The waist features a full elastic design with an internal drawcord, allowing easy fit adjustment without a belt.
Belt loops are also included, making it suitable for more polished styling. The front uses a hook closure with a button fly, giving it a smart trousers look.
Slash pockets on both sides and a single welt pocket with a button at the back enhance practicality. Comfortable to wear, yet still looking polished—this balance is what makes the design stand out.
A center crease on the front emphasizes vertical lines, creating a clean and streamlined look even with the wide silhouette.
A Rounded, Dimensional Wide Silhouette
The side seams create a subtle curve, forming an “egg-shaped” silhouette. Rather than simply wide, it offers a dimensional shape that adds natural depth to the overall look.
While providing ample room through the waist and thighs, the center crease maintains a strong vertical line for a balanced appearance.
Combined with the lightweight spring–summer fabric, the pants offer presence without heaviness—making them a reliable wide slacks option for refined adult styling.

●Staff Height / Weight: 165cm / 64kg Wearing size: 44 Body type: Slim (narrow shoulders) Fit: Relaxed Length: Slightly long I usually wear between S and M, and size 44 fits comfortably. The waist has a moderate amount of room and feels secure even without a belt. The rounded “egg” silhouette from the hips through the thighs is clearly defined, giving the pants a relaxed look. The length is slightly long with about one break, but the lightweight fabric keeps the overall appearance from feeling heavy. A good option for slimmer builds who prefer a relaxed fit. |

●Staff Height / Weight: 171cm / 70kg Wearing size: 44 Body type: Standard Fit: Relaxed Length: Just right I usually wear the equivalent of size M, and size 44 fits just right. The waist is well balanced—not too tight or too loose—and there is a natural amount of room around the hips and thighs. The length creates about one break, making it easy to pair with both sneakers and leather shoes. Size 44 corresponds roughly to a standard M size. |

●Staff Height / Weight: 177cm / 73kg Wearing size: 46 Body type: Standard Fit: Relaxed Length: Slightly long I usually wear size L, and size 46 provides a comfortable amount of room. The waist fits fairly close, while the hips and thighs create a nicely rounded silhouette. The length is slightly long with about one to one and a half breaks. Size 46 corresponds roughly to a standard L size and works well if you want a slightly fuller, modern silhouette. |

●Staff Height / Weight: 181cm / 78kg Wearing size: 48 Body type: Solid build (broad shoulders) Fit: Relaxed Length: Slightly long I usually wear between L and XL, and size 48 fits comfortably. There is no tightness around the waist or hips, making it suitable even for a solid build. The roomy thigh area allows for easy movement and gives the pants their natural egg-shaped silhouette. The length is slightly long, but the proportions still look balanced for a taller frame. Size 48 corresponds roughly to an XL fit. |
