I previously mentioned this bug over on Havelock's Tailor and Costume Issues thread:
http://sto-forum.perfectworld.com/showpost.php?p=14606761&postcount=254
I'll rehash the post here in the proper part of the forums along with pics to serve as proof:
It appears the new Reman skin textures for the chest and the arms were not included by the devs for the Dilithium Miner costume. I just purchased mine today, and after setting it up, it fails to show the part of the character's bare upper chest for the open v-neck portion of the undershirt. Also, the arms are invisible for the short sleeve version of the shirt from the sleeve down to the hands (the hands are visible, however. Is someone a fan of Rayman over at Cryptic perhaps? :P).
This problem persists in both the Vest category version (

http://tinypic.com/r/v5eliu/5). However, the Jacket Tight version with the long sleeve undershirt DOES show the upper chest skin texture that is missing in the other versions strangely enough (
http://tinypic.com/r/qps1eo/5).
I reported this bug via Holodeck,
ticket ID #2,257,449.
Since I do not have a male Reman on my account, I'm unable to check to see if this problem persists for that gender in the miner's outfit. So far I have obtained the outfit for my female Andorian and female Ferasan characters with no noticeable graphical glitches.
