Short Sleeve Boxy Shirt
Overview
We understand that ready-to-wear sizing may not always offer the perfect fit for everyone.
At Lounge Sai, we provide professional alteration services and specification adjustments for garments purchased from our store.
Our trusted artisans perform all alterations with careful attention to each piece’s original design, detailing, and fabric characteristics, so you can entrust us with your valued garments with peace of mind.
Examples of Alterations
For instance, we can shorten sleeves that are too long, or lengthen sleeves that are too short, depending on the garment's specifications.
If the waist of a pair of pants is too large, rather than simply reducing the waistline, adjustments are made with careful consideration to balance the overall silhouette — including fine adjustments to the rise and width — to ensure a natural, refined finish.
Below are some examples of alterations we have done in the past:
- Sleeve shortening or lengthening for coats and jackets
- Waist adjustments and hemming/lengthening for pants
- Shortening long shirts to a standard length
- Adjusting the size and depth of pant pocket openings
- Changing hems to a raw edge finish
We may also be able to handle complex alterations that other stores have declined.
If there is any part of a garment that you are concerned about, please feel free to consult with us to ensure you can enjoy wearing your piece comfortably.
Pricing and Turnaround Time
Pricing
The final cost will be determined after we receive and assess the garment, as the complexity and method of each alteration can vary.
However, as a general guideline based on previous cases:
- Simple alterations such as hemming: approximately ¥4,000 (tax included)
- Complex alterations: typically within ¥10,000 (tax included)
Turnaround Time
- Standard period: approximately 2 weeks
- During peak seasons: approximately 3–4 weeks
If you are in a hurry, please let us know. We will do our best to accommodate your request when possible.

A fabric I particularly liked this season—a lightweight, earthy multicolored check with a gauze-like texture.
While a long sleeve shirt made from the same fabric (Easy Shirt) was released with slightly altered specs, this short sleeve version wasn’t originally part of the collection. I requested a custom production of this fabric in a short sleeve boxy silhouette exclusively for our store.

As the name suggests, this shirt features a wide body and short length, forming a clean boxy silhouette.
The relaxed fit extends through the arms, with sleeves long enough to cover the upper arm—similar in length to rolling up a long sleeve shirt, but much more breathable and airy.



Two pockets sit on either side of the chest, and the buttons are matte black horn. Leave the top button undone, and air flows through for an incredibly lightweight feel.
Made from a blend of 86% cotton, 12% viscose, and 2% linen, the fabric becomes even softer with wear—developing a brushed, almost fuzzy texture that hugs the skin.

181cm / Size M
Paired with full-length trousers, the cropped length stands out as a styling point.
When indoors with air conditioning or transitioning into cooler seasons, layering a jacket over it works perfectly.
Though the pattern may seem busy at first glance, the earthy tones balance well with bold jackets or colored trousers—making this shirt surprisingly easy to incorporate into a variety of looks.
