The Scene
If you go to work with short sleeves, you will be cold in the air conditioner, and if you wear long sleeves, you will be hot outside.
MONSEN's Office AC Ready proposes a layering formula that doesn't lose its neatness even
in this temperature gap.
Why this edit works
Cold indoor air changes how a work outfit feels.
This edit focuses on light layering, calm contrast, and office-ready structure—so you stay comfortable without looking bulky.
The Problem
If you only wear a short-sleeved shirt, your shoulders will shrink in the air conditioning
Wearing a jacket makes you sweat when commuting to work
Knitted vest? Good choice, but difficult to combine
Summer suits are worried about wrinkles and reflection

Note i.
The temperature difference between the inside and outside the office is more than 10 degrees. A cardigan or shirt jacket that is easy to put on and take off is key.
Note ii.
The biggest mistake of summer shirts is reflection. The right thickness and inner selection create a reliable impression.
Note iii.
If the top is cool, it is not enough. One breathable slacks will make the difference for your condition throughout the day.
