Winter Undergarment (Hadajuban) - With Flaws

This item was found stored in my parents' old shed and I believe it's quite old, though I have no idea exactly how old. It was unearthed from deep within a shed that's nearly 70 years old.
It appears to be new and unused, but due to age-related deterioration, there are stains and dirt, particularly around the lace on the cuffs.
These might come off with a color-safe bleach, but please understand that this is a difficult item sold as-is.
It will be shipped in simple, waterproof packaging only.
