I have a BNWOT size 30 14oz Natural Tan Corter Leather belt for sale that I got from Blue Owl that was too small. It's new and only tried on 3-4 times at home. It fit my friend who wears size 27 APC New Standards or Cures, but the folded part at the buckle was too thick for his belt loops.
Yours for $40 before shipping. Photos in the link below, but let me know if you want photos of mine.
I have a pair of dior homme blacksuns that I bought at the dior store back in march. I haven't worn them much and they've been washed once. Unhemmed. There was a small hole near one of the belt loops (shown in the pictures) that is pretty unnoticeable and has been repaired.
Interested in trading them for black super slenders in 30 or other dior homme 17.5s.
