DISCLAIMER:

Just to clarify, you DON't NEED to post all this stuff in the prompt to get the character. All of these tags is only if you aim for a more or less accurate depiction of the costume. And I say "more or less" because forget the AI I myself can barely tell ascensions apart.

Something around the lines of "revealing clothes, detached sleeves, black sleeves" is more than enough for basic gens.
