May I suggest black underwear to prevent (visible) staining. That's always what I did. In fact, it just occurred to me the other day that I no longer need to collect black underwear like it's going out of style. Yay!

Back when I was still wearing women's panties, I used to really, really hate it when I would buy a pack of underwear, only to discover that some idiot had decided it would be a good idea to line all the black underwear with white fabric.

But back to the original topic ...
For the first time in my life I've become something of a clothes horse.

I've become totally addicted to clearance racks. In fact, I just picked up a couple dress shirts ($4.50 each!) and long-sleeved T-shirts ($2 each) at Kohls yesterday.

5 or 6 pairs of jeans (I go through these quickly, so I loose track. My job is pretty rough on clothes.)
2 pairs cargo pants (black and brown)
3 pairs of dress slacks (Brown, grey, black)
5 pairs of shorts
1 pair of swim trunks
4 pairs of fleece pajama bottoms (Even men's sleepwear has pockets!

)
4 pairs of corduroy trousers (brown, black, tan, grey)
8 dress shirts with convertible cuffs (gold, grey, black, red, purple, blue, brown, burgundy)
2 dress shirts with French Cuffs
A dozen, or so regular-cuffed dress shirts
Half a dozen-ish silk shirts
3 flannel shirts
15 or so long-sleeved casual button-up shirts
15 or so short-sleeved button up shirts (although most of these are now too big for me, so I need to get some more.

)
3 sport coats (black, grey, brown. Still need a Navy one.)
3 light-weight leather jackets
4 hoodies (red, black, blue, orange)
Winter coat
Nice trench coat, with removable liner, for more formal occasions
Custom painted leather rocker jacket that I got in London on my 18th birthday.

40 or so ties
A couple dozen fashion T-shirts (with graphics)
A dozen or so long-sleeved T-shirts
A dozen or so solid-color T-shirts in various colors.
4 or 5 baseball caps
3 cadet caps
several newsboy caps
a black Homburg
a black Feodora
a brown corduroy Trilby
a pinstriped Trilby
a brown Safari hat (which I'm going to try to sell, as it's a bit big.)
a black Top Hat (which rarely gets worn)
5 pairs of cuff links
3 tie clips
1 pair of sneakers
1 pair of black sandals (I'd like some brown ones as well.)
1 pair black oxfords
1 pair brown penny loafers (which I plan to replace with saddle oxfords when I get a chance)
2 pairs slip-on skater shoes (1 brown, 1 black pinstriped)
2 pairs steel-toed work boots
several pairs of shoes I rarely wear, except on costume occasion - motorcycle boots, moccasin boots, silver loafers, etc.)
genuine fleece-line slippers (a necessity here in the frigid north)
lots and lots of boxer-briefs, 3 pairs of trunks (which I'll be getting more of) and 1 pair of boxers.
Ummm... That's all I can think of off the top of my head.
