However, overall, I consider it to be a vintage overall in remarkably good condition.
However, this is merely my personal opinion.
There are individual differences in how things are viewed.
Please refrain from purchasing if you are not used to used clothing, as this is a vintage item that has aged over time.

I have carefully checked the item and have described any areas of concern in the description.
However, there may be assorted minor oversights.
Please consider that this is used clothing managed by an individual, not a discover.
