There are but a few naturally red monk it3ms, unfortunately many of them are out of your reach at the moment. You could start with the
Sarnak Emblazened Tabard or do the Freeport quest for a
Reserve Militia Tunic, I believe that has a red chain look. The problem with those items though is that they are pretty heavy and will heavily contribute to put you over the monk weight limit, which at level 17 is 15 stones. After that you begin to lose ac. You don't want that.
So here's what I suggest, if you want a red monk look, go to the Luclin Bazaar and purchase Vials of Prismatic Dye and do a /bodytint, set red up the 255 and green and blue down to 0 for you chest slot, head, wrists, legs, arms, gloves, and feet. You will achieve your desired reddish look.
Comment: WTF? You have filtered out the term "monk it3m"? That's crazy!
