And They're Off.........

It's been going on for years and it's about to start again: my annual search for a pair of white trousers (pants) that are not transparent.
Sounds so simple, but I have tried chinos, denims, linen mixes; fully lined and semi-lined and not at all lined. And every single pair has revealed that which I choose to leave unseen: my knickers.
I've tried endless brands and endless stores including Nordstrom, Dillards, Macys, J. Crew, J.Jill, Talbots, Gap. I thought the, cough, 'older lady' retailers would have this dignity issue sorted, but no.

First the pants have to pass the held-up-to-the-light test.
On the couple of occasions when the pink of my skin or the hue of skin-toned knickers has not shown through, I've been flummoxed by the other problem: visible front pockets - two contrasting half-moons spoiling what should be a smooth white surface. I once read a tip that suggested cutting out front pockets to avoid the messy look, but it's a tricky and expensive alteration.

So, any suggestions?
I know about wearing 'nude'-coloured undies; I can't do haute couture; I'm looking for the wide-leg Kate Hepburn style or the classic straight leg jean. Pubic-exposing skinny is not for me.

So if you try on a pair of whites that fit the bill, be a doll and let me know, will you? The person who helps me finally shut up about this will be rewarded with my eternal gratitude (and that of my husband), a huge shout-out and something delectable in the mail that goes with white pants - I was thinking chocolate....a set of indelible ink pens....that sort of thing.
