I wear normal lycra gear - tho' with the weather at the moment I'm also wearing Craft/Descente 3/4 zip tri tops 'cos the underarm venting (actually none, cos there's no fabric there) is very welcome - tho' they're also a close fit, which may be making me sweatier anyway....
A few of those are mesh backed too, tho' on the Speedmachine seatpad (the more ventisit-like version) I'm not sure it makes that much difference - most of the heavy sweat seems to collect on the front. The pockets are kinda love-handle level,so might actually be useful - not sure I'd actually want pockets right on the front.
The bib longs I have (lusso coolmax/roubaix) work well 'cos its just double thickness in the seat rather than having a pad - likewise a De Soto trisuit. (The (cheaper end ?) Nalini bib shorts I normally wear could do with a little less padding, but they're mebbe at the thinner end of the market anyway)
One thing I have noticed is in dodgier weather, even with roubaix, is that the backs of the thighs seem to notice the cold/rain first. Not sure why, but I think my knees tend to fell colder than on a DF too. Tho' that has been on particularly cold days, so mebbe they'd have felt v.cold regardless.Certainly windstopper over the backs of the thighs might be welcome, tho' when there's much rain, something that sheds it over the front of the legs/back of the thighs would be good, Dunno if you could make it highly breathable tho', otherwise I'd just get wet from the inside !
FWIW, my mother - many years ago - once bought me a pair of (red!) lycra (running ?) cycle-style shorts without any padding. Positively pornographic without underwear

- I think you need something like double thickness/heavy lycra in the crotch if yer undie-less
Re waterproof/winterwear - smock style would be good. I tend to aim for wet/warm, but after one particularly wet/cold day just before Christmas I was intending to look at some buffalo or montane pertex/pile gear before the winter arrives.
Edit: re jerseys - kinda stylish would be good, I've got enough normal ones that do 95% of the job that I'd have to *want* to buy a recumbent-specific jersey.
