I have tons of crossdressing mistakes. Among them include numerous times of leaving some kind of women's item out (that of course I believed I had meticulously looked for) loose false nails, panties, stockings lipstick ect. Always seemed to find them laying out at unfortunate times

I too had an eyebrow mishap and trimmed way too much off one eyebrow. Being creative I came up with the ol "put too much charcoal lighter fluid on the grill and experienced a flashback that burned my eyebrows off." Kinda worked.

As others have stated I wish I had had the big talk with my wife sooner.
