OK, you can’t use gains or the choice name option method in CC templates however I tested out this code in regards to 14 outfit choices:
label Dressing
NARR
Pick something.
choice(OUTFIT)[shouldPaginate: YES]
“1”{
}“2”{
}“3”{
}“4”{
}“5”{
}“6”{
}“7”{
}“8”{
}“9”{
}“10”{
}“11”{
}“12”{
}“13”{
}“14”{
}
NARR
U happy with this?
choice
“Yes”{
}“No”{
goto Dressing
}
NARR
Remembering it…
if (OUTFIT is “1”) {
NARR
U chose 1.
} elif (OUTFIT is “2”) {
NARR
U chose 2.
} elif (OUTFIT is “3”) {
NARR
U chose 3.
} elif (OUTFIT is “4”) {
NARR
U chose 4.
} elif (OUTFIT is “5”) {
NARR
U chose 5.
} elif (OUTFIT is “6”) {
NARR
U chose 6.
} elif (OUTFIT is “7”) {
NARR
U chose 7.
} elif (OUTFIT is “8”) {
NARR
U chose 8.
} elif (OUTFIT is “9”) {
NARR
U chose 9.
} elif (OUTFIT is “10”) {
NARR
U chose 10.
} elif (OUTFIT is “11”) {
NARR
U chose 11.
} elif (OUTFIT is “12”) {
NARR
U chose 12.
} elif (OUTFIT is “13”) {
NARR
U chose 13.
} else {
NARR
U chose 14
}
NARR
Bla bla bla.
So…yeah it worked perfectly for me, all 14 ones were memorized in this dressing game when i tested it on portal 
But I agree with you, it would be too much to memorize, if there are sooooooooo many outfits since [shouldPaginate: YES] should be reserved for a lot of options XD
OK for this part, U can use gotos inside of if/elif/else statements but not labels.
