I have also use Tailor 1.1 and I must agree that with some mesh it work out quite well but not with others. To be fair, I think Tailor 1.1 is written base on DAZ Victoria and the Victoria clothing Pak 1, so if you use most of them should have no problem and require just minimum morph and tweaking. However this may not be true for other clothing as new items come out everyday. I also agree with lalverson that so far I am not able to find any step by step tutorial for any specify clothing. However, while exploring all the comments here why not try using magnets on the clothing. I think so far Wyrmmaster's mastery has demonstrate the power of this technique. Besides I think this technique is more straight forward. So try and use it on the cloths for minor adjustment. I am no expert myself but I have use this technique to make small adjustments in clothing so far. Moreover, there are definitely more step by step tutorials for magnets than Tailor1.1. Alternatively, if you are Poser5 user, you may want to try dynamic clothing.
