I only saw the last part of this Anime. A few minutes. So, I cannot give many details. I think it was a movie and I think it was around the 2nd half of the 1990s. Because it was on a weekend program where they showed Anime movies and once "X (1999)" was one of them.
What I remember from that short scene:
- The Anime is about people, who can transform themselves into giant robots with the help of a device/talisman (?). However, the transformation rips their clothes apart and when hey change back, they are totally naked.
- The protagonist is a girl. She has straight, shoulder-lenght, brown(ish) hair and she wears it in pigtails maybe. Anyway, her hair is tied up somehow. Either she cannot transform till the end of the movie or she has problems with fighting... but in the end she transforms and fights well.
- There is and older guy (not old!), who may be her "teacher", who teaches her how to transform(?) He has brown hair and glasses I guess. In that end scene he came to help the girl out but she did well on her own, so he just watches and changes back. Being experienced, he brought spare clothes with him, but there is a giant dog (I think it is his) that takes them. So the guy ends up chasing the dog naked. They were under a bridge that time.
- The art was great and detailed.
This is ALL I remember.
