I used SQLlite to edit the database and below I typed up a quick key of the costume locations I've identified. Since upperbody and lowerbody in the region tab isn't always crystal clear. Some costume part names are not as simple as: "helmet" or "goggles"
Here's a part key for the database. Example 0 = pants so in the part column row 0 you would add pants costume information into the database. 1 for chest, etc. I have circled part number in Red

Database Geometry locations
0 = pants
1 = chest
2 = head/face
3 = gloves
4 = boots
5 = belt
6 = hats / hair
7 = ?
8 = head wings, bull horns, glasses, goggles and eyewear
9 = chest detail, emblems, chest plates, chest gear. Not to be confused with tights chest detail
10 = shoulders
11 = backpack / wings
12 = right claws weapon
13 = neck detail, such as Diabolique's collar
14 = ?
15 = Cape top / mantle
16 = ?
17 = cape
18 = aura/path aura/glowing or burning eyes, etc
19 = shorts/skirt - not to be confused with old tight bodypainted on skirt/shorts
20 = jackets / trench coat / shirt
21 = sleeves
22 = ?
23 = ?
24 = left claws weapon
25 = ?
26 = ?
27 = tails, phoenix tail, animated tails
Changing Costume Colors in the database:To change colors of your costume parts and FX. You will need to use Blue Green and Red format like the normal costume files use and take the 3 numbers; Multiply blue by 65536 green by 256 and add them together. White would be
255,
255,
255 =
255*65536 +
255*256 +
255 = 16777215. Take that final number (in this case for white) and place it in the first color tab if that was your primary color. Refer to my picture above if you were wanting color one of the pants to be white. You'd place it in the same row as the pants geometry in color 1 column. Thank you Leandro for the explanation of changing color.
