Wu's armor is included in this, although I think it's already era keyed correctly. But the rest of the silk line (Raw silk, Cured silk) wasn't tailorable until September 1999 either.
Mentioned here in this Guide forums post crossposted to the eqbards mailing list:

 -New tailoring items have been added. Tailors can now make the silk series
 of armor. The books on how to manufacture these
 are also in the game, but are spawn drops and not vendor sales.

 And again in the eqbards list a bit later on:
EQ-Monks mailing list also talks about this in October 1999 that implies it's clearly a new set of armor added recently:

 Subject: cured silk and other delights
 
 I've found the debate about pulling interesting, as I just reached 17th
 level and can start appreciating the feign death skill. It already saved me
 once today, so I'm very grateful for it.
 
 Cured silk armor has been mentioned a bit here, but not too much. I was
 curious about people's opinions on it. I for one think it's a wonderful
 thing. Finally monks have a look that is unique, even at lower levels (for
 those who don't know, cured silk and shiverback look the same). Cured silk
 has the same AC as mesh, although it isn't magic in its native form (so
 keep your mesh gloves for fighting). If you're out to buy silk armor, make
 sure you're getting cured, not raw silk.
 
 It's true that cured silk doesn't provide the stats that some of the game's
 unique mob-obtainable items do (silver plated bracers, Lockjaw vest, etc.),
 but when Enchanters gain the ability to enchant this armor, I think it will
 become one of the best armor sets in the game. Monks need stat boosts with
 their equipment, since our choice in armor is so limited. Even moderate
 boosts to our abilities via enchanted cured silk will be wonderful.
 
 It's a little unfortunate that we don't have the ability to change the
 pants to a different color, but there is room for customization. I have
 cured silk on my upper body but kept mesh pants and fur-lined boots. This
 gives me a black colored lower half, which I think looks better than the
 yellow-tan look of all cured armor.
 
 Something I haven't seen mentioned on the monk web sites is Gauntlets of
 Wu, another item exclusive to our class. This is a tailor-made item, which
 results in magic gloves that give off the light of a greater lightstone (a
 GL is required for their creation). They have the same AC as mesh. What's
 the big deal, you say, I can just wear mesh gloves and carry a GL for the
 same effect. True, but these gauntlets are a must for several reasons: 1)
 Any monk-only item is cool to have. 2) They have a neat graphic in your
 inventory. 3) Awesome name! Finally, equipment named to make sense for a
 monk to have.
 
 After running around looking like a low-level fighter for most of the game
 (even though I was supposed to be wearing magical armor), it's nice to have
 a look all our own. These days I'm loving being a monk.

 Finally, Raw Silk is also mentioned as new in the EQ-Monks list:

 There is new armor in the game... it's Raw Silk Armor.
 Here's how you make it:
 
 Take 2 spider silks, put them in your sewing kit, hit
 combine.
 
 Then take the silk swatch you just made, load up a
 pattern, and hit combine.
 
 Viola... silk armor. The tunic is actually a brown robe
 that we monks can wear. It's AC6.
 
 Swatch was trivial for me to make at my tailoring skill
 of 28... dunno where trivial starts. The robe I made
 was NOT trivial yet. As silk is a lot easier to get
 ahold of than studs, this is great news for us budding
 tailors.
