Maybe it sounds futile but I really would like to know where I can buy some silk boxers.

Try 1 of the Indian tailors.

If not a stock item, they would surely make for you.

They are suprisingly, quite hard to find.

The Jim Thompson outlet store at Homeworks South Pattaya has some...( expensive though )

but you could buy some silk from them and take it to one of the many tailor shops behind and to the left of Tuk Com for them to make some shorts.

Thanks for the information. Can't I just buy the silk directly from the tailors near Tukcom as well? (or are they going to rip me off?)

I would trust the silk to be real silk at Jim Thomson and they have a lot of different colors /styles there

but you can probably find the real stuff at the tailors.

Some of the gay clothes stores in Jomtien Complex stock them.

No to Jim Thompson's, the silk is fine, the way they are made is not.

Be sure that you get a pair (or specify to the tailor) that do not have the seam running up the middle of the back of the shorts. It's the cheapest way to make a pair of boxers (the way Jim Thompson's does it) and it's also the worst (most uncomfortable) way.

How much should I expect to pay? Do you recommend one those tailors near Tukcom in particular?

Some of the gay clothes stores in Jomtien Complex stock them.

They're going to rape me if I go there...

I found loads at the Indian tailors along second road.
