Kevlar jeans don't disintegrate when sliding across road surfaces like regular jeans do. They also don't have any armor so you take the hit full on.
You missed that there are padded/armoured under shorts and shirts that one can and should wear with the jeans.
Still not quite the same level of protection as the best full armour ... but is much more comfy and comfort is very much a factor on long rides.
As to the OP's question,
-In textiles, oddly enough, Joe Rocket seems to fit the ladies very well and many really like the styling.
-For Kevelar Jeans, Sliders are the best bang for the buck, imo.
-Armoured underwear? Cycle Gear or Motorcycle Superstore have a good variety to choose from.
If your preference is leather, my first recommendations are what to watch out for/ be wary of.
There are many companies that sell leather "motorcycle" jackets that are just paper thin fashion statements.
The companies that do make thicker (actually protective) leather riding gear tend to go to the extreme ends of the style spectrum.
You get to choose from Hardley cruiser zipperhell jackets or Proracer wannabee squid attire.
You might find some classic or vintage style Hein Gericke Leathers.
That would be my best suggestion. Not thrilled with some of the newer styling but usually does come with good armour.
And lastly, Whether you buy new or used, check the armour paddings rating. You will find that many have the older style pads.
When looking, make sure the pads are not jus CE approved. You want CE en1621-1 or en1621-2. En1621-2 is the newer standard. If you find an older set that you really like you can by the newer pads to improve your protection.
This is something you don't hear much about but riders should probably be buying new armour pads about as often as we buy helmets, and for the same reasons.
Hope this helps,
