Comparison Fit Photos: Moose Knuckles Ballistic Men's XS vs. Mackage Dixon Size 36

My house was a total mess in the Moose Knuckles Ballistic photo, but that was back in March 2025. Please note that as you can see in the Mackage Dixon photo taken a few days ago, my house is now well-organized.
I bought both secondhand for 200,000 KRW, but the Moose Knuckles Ballistic ended up being in such bad condition and smelled so bad that I had to throw it away (these are the fit photos from before I discarded it).
I tried to find another Moose Knuckles Ballistic Men's XS, but I couldn't find any listings anywhere, so I purchased a Mackage Dixon size 36, which is supposedly the same domestic size 90.
People tell me that if I'm wearing a Dixon 36, I should go for a Ballistic Men's S, but in my experience, the Ballistic Men's XS actually feels slightly larger than the Dixon 36. Is it just me?
Doesn't it look that way in the photos too?
For the Moose Knuckles, I only wore a short-sleeve shirt underneath, and for the Mackage, I only wore a long-sleeve shirt.
