Typo/misspelling: Change garmet to garment.
I recommend deleting out there from the first sentence or changing in there to underneath one in the second sentence. Better yet, pare down the beginning of the first sentence, removing nonessential words.
Of all garments, kilts are the best for hiding knives. You can hide a ton of those suckers underneath one.
(I could tell you why I know this to be untrue, but then you’d ask for evidence…)
