I used to buy my knickers singly; plain cotton ones. Then a $2 shop opened and I saw pairs with pretty flowers also cotton mix. And they have lasted far, far longer than those I paid through the ..er...gusset for.
Unfortunately, the inconsistency of stock has meant that recently when I went to replace a pair or two, they only had nylon ones. :-(
I bought just one pair and they are so long in the body I could easily wear the waist band under my arms and still have all my bits covered.
LOVE 'granny's fatty knickers.'
Just as an aside. I haven't seen it here but so many people seem to refer to 'front bottoms' as the vagina. Shows a shocking lack of knowledge about the female body.
You would not, unless you are a gynecologist see a vagina.
The 'lady bit' referred to is mons pubis or just 'mons'.
