Yep, yep exactly. I used the sacred ashes robe before, which was a more moderate version of her vanilla outfit, but this is muuuch better.

It changes up her skimpy default robe into something much more sensible and practical, while still staying true to the original design. Hence the name of the mod:

Practical Morrigan Robe

I like it! It incorporates the iconic parts of her vanilla costume but looks like something she'd actually wear.
