Got 2 pairs of the new skinny jeans (the ones that replace the T000) and I have to say that I'm impressed. I freaked when I heard they were being discontinued and bought a bunch of the black t000s, however these new ones have a nicer, mor flattering fit and a heftier cotton weave. It's true that they come with a bit of a sheen, but after one wash it goes away dramatically and you're left with a solid pair of jeans. These "new" jeans don't have the massive stretching issues that the T000s in black did, so that's nice. Also, the leg opening is a bit slimmer (about 6.75" for a size 31, compared to 7" on my old T000s).
Overall, I actually like these just as much, if not slightly more due to the refined fit and non-massive-stretch issues.
Keep in mind, the sheen only applies to the black jeans. The grey ones that I bought are perfect.
For sizing - I wear a 32 in Levi's and got these in a 31 and they fit perfectly. A bit tight at first but they stretch out slightly within a day or two.
Also, their dry-mesh shirts are awesome (order TTS). The collars are a bit constricting on the crew-necks, so I found the v-necks to be more comfortable for gym-stuff.
Finally, for those who still have slim-oxford sizing questions, go TTS on the slims. I have a 39" chest. I wear a small in JCrew oxford, but needed a medium in the Uniqlo slim oxford. The small was just uncomfortably restricting. I'm 5'11" and it's just a touch too long - very simple alteration if you plan on wearing it untucked regularly.
Hope this helps anyone in a similar situation.
Maybe the grey pair I got was mis-tagged or some sort of screw up but they fit tiny. Like a full size smaller than my t-000s that I bought last spring and fall and way smaller than the same size in levis.
