Hmm... I think your description is a bit too vague, a silk top can look like anything... could a silk texture be applied to an already existing mesh? Maybe if you post some pictures we can get some idea what you're looking for.
Here's a pic Warlokk. I like the shirt in the middle, but I like the silk texture on the blue top. Any shirt mesh that's similar to these shirts would do. I would like the shirt to reach down to the top of the belt line on these jeans, like shown on the middle shirt and blue shirt. Thanks for you interest. Also do these jeans come in your 36 hip size?
