>>1650852Though, now that I think about it. While not exactly the same concept, Ultimate Girls was a great mix of Giantess and ENF. Of course, it's also an Ultraman clone. They don't grow out of their clothes, but their outfits constantly shrink/dissolve over time, and their power comes from MOE (or in this case, getting embarrassed over the fact that they're gonna be seen naked).
