Paramo style top help please

After wet week-end experiment I think it is time to have a go at making a top.
I have some metres of EPIC fabric and I can use this as the outer.
I also have some cheap polyester mesh, some old Paddys Dritec mesh and some stiffer lightly resinated mesh in my cupboard.
I prefer pullover tops and I like a long length.
his will be a mid-layer and i want to leave enough room for at least 2 sets of underwear.
How should I size these?/ I haven't ever examined a real Paramo top to look at the cut and I cannot decide on the correct fit Loose and baggy or cut closer??
Will I need pit zips ? or am I better off with slit hems opening from the bottom and a half zip to the waist line ??
how many layers of mesh? The stuff I got from Paddys is brilliant at moving sweat and in a top over a long-john under a windproof provides just enough insulation for fast skiing.
A lot of questions and I'm hoping some-one in the community has the experience to help me decide on the best design
