You could swear you need something more... But not in the cloth department. Some people might find yours to be plain, but that just because they don't understand how true beauty work. Clothes don't simply need to enhance someone physical beauty, they also need to reflect their wearer's personality while suiting their needs. To resume, you were tastefully dressed and didn't care about the naysayers who think otherwise!
But if it wasn't your clothing, what was wrong? What more could you need?
Suddenly, you think of the few drawings of succubi you ever saw. Every succubus had something you don't: Wings.
"Say captain, you wouldn't happen to have wings for me, right?"
Said captain seem a bit hesitant about your choice. "Wings? Are you sure it's what you want?" But a stern look convince him he couldn't dissuade you. "Okay, follow me please" he say, resigned.
You followed the captain to some sort of workshop. On the walls were shelves full of bits and parts of mechanical nature. Most people would just assume those to me some metal junk but, thanks to your kin eyes when it come to all king of tinkering, you see it is possible with all this to replace almost every part of an humanoid body by mechanical equivalents several time over, and then some.
The captain stop in front of a work bench, taking a small crate from under it "This come from a cancelled project. It wasn't intended to be used as prosthesis, but with a bit of tinkering…" You look inside the crate to see aluminum blades assembled to make the bonny part of a bat wings. The top part of this metal frame seem razor-sharp, but whatever material he want to use instead of skin won't be in contact with it.
You watch him work on your futures wings, understanding more and more how his technology work as time pass, and you find it very impressive.
Then, without warning, he take the wings, still without any material to replace the leather their inspiration has, and place them on your back. You feel an excruciating pain in your spine and shoulder blades as they become part of you, somehow creating a clean keyhole in your shirt.
Once the pain faded and the wings fully integrated with your body you look back at them. Noticing they seem to use your own leathery skin, and since you didn't have wings before, you wonder for a moment where it came from. Then you shake your head in disbelief. Of course you already had wings! Why did you think other wise?
Now you notice the tip of your tail. You don't like how it end in a spades. You voice so, asking if you can use this workshop to do something about it yourself, but don't wait for any answer.
The captain watch in disbelief as you build what look like the barrel of a gun, but with its end obstructed by some sort of glass. The thing will shoot a thin but concentrated ray of photons disintegrating anything in its path, using a bit of your magic source energy. Or in layman terms, shoot a laser. Then, you put on each side of it a blade as sharp as your new wings, then mount it on what look like a mechanical version of the articulations between each bones of your tail. This enable you to add a metal replica of one of you tail's bones, which again is decked with two blades on opposites side, blades you take great care to perfectly align with the two on the laser shooter, while making sure the blades wont touch each other. Satisfied, you add an identical vertebrae.
Your project now finished, and since there is no scalpel around, you use a knife to split your tail open, taking great care to not damage any nerves or blood vessels, and preserve as much muscles and skin as you can. Blood so black it seems eat the light around it is now flowing out of your tail, but you simply take the spade and the first vertebrae following it out of there, like it was nothing. You then put the artificial tip you just built for your tail in its stead, taking care to properly place each nerves, blood vessels and muscle, before finally closing this self inflicted wound, which instantly heal.
"Thank you kindly, captain. How do I leave your ship?"
