looking2grow: Wow, that’s a tough one. I really admire you for wanting to improve ur tznius. I don’t think any of us can pasken correctly, since we are not exactly rabbonim. I heard that you’re supposed to wear four inches below your knee. The point here isn’t inches though. Bottom line: your knees must be covered at all times. If two inches isn’t enough, then phrase your shaila this way. Say it doesn’t really serve the purpose.
Hatzlacha in whatever you do!!!!
