I think this is it. I am now considering comfort where my knickers are concerned above everything else. I've worn all sorts over the years ( at the g-strings I wore in the early noughties).
I love my Firm Control Full Briefs. They're pure cotton, hold me in and are exceedingly comfortable, but they do remind me of what my late DM used to wear. They only come in white, flesh and black - uber functional (although I did once get a pair in the two pack with a teeny tiny pink chintzy floral pattern on, so bad they shouldn't be mentioned on this board)!
Is this it? I also like visiting garden centres and watching the Antique Roadshow.
