[X-Men Movies] Let's talk about Mystique's powers.

In the first film, when she fought Wolverine as Wolverine, she had claws, we learned that they were obviously not real claws because they got lopped off, and she screamed. But she didn't lose any noticeable parts when back in blue. 

In the second, when she snuck on top of Logan pretending to be Jean while he was sleeping, I believe Logan found the scars from their fight in the first movie, how or why are there even scars formed? ESPECIALLY when transformed?

Additionally, let's talk about clothing. She makes clothing out of nothing, so basically her skin, yeah? So she can't disrobe, since that'd be in essence literally cutting off her own skin, right?

Mystique doesn't have the same body that me and you have. We have voids and spaces and bags full of fluid and all sorts of non-tissue locations in our body. Mystique doesn't have such issues. She's a big mass of cells that can be whatever cells they need to be, or whatever she wants, as long as the form is roughly humanoid. 

Her losing the few bits of her flesh from that injury is not enough to diminish her form. Like you can live without your appendix, uvula and several other parts, she's okay missing a pound of flesh, and it will likely grow back rather quickly.

Now, as to the scars, Wolverine stabbed her his claws, which are constructed of Adamantium Beta, the same alloy that is bonded to his bones. It is notoriously poisonous to humankind, and perhaps in Mystique's case inhibits her healing ability to the point that that area on her would have a scar for a while.

Mystique wears clothes all the time. She only uses her flesh as clothes when it suits her to do so, and not for any extended amount of time. If by chance she is making clothes out of herself for some reason, 'removing them' would not be possible.
