Hi. I've never made a mesh so I really don't know what I'm talking about. Please bear with me

I was wondering if it's possible to make a Maxis full dress into a skirt. There's a dress that came with Uni that would suit my purposes much better as a bottom piece rather than an entire outfit since I'm planning a clothing line of mix and match items.
Also, I know this last bit may be a stretch but here goes anyway, would anyone be interested in creating this mesh for me. If so please pm me.
Thanks for any advice you can offer
