My experiences with textile gear... I have a friend who crashed at 20mph wearing a good quality textile jacket and pants, and the pants ripped where he slid, and the jacket ripped and the armour was shifted out of the way. He got quite a bit of road rash on his arm, but his leg was ok. This was 20mph. Even good quality textile can have possibly very little abrasion resistance if you slide rather than roll. I think a lot of people fall off and roll and everything is fine, but a good slide can get through textile very quickly.
I wear a 2-piece zip together leather suit, and I hit some oil doing about 80km/h in a turn, and you can barely see the marks on the leather where I went down. And the armour worked well too, had one bruise on my arm and that was it.
Get the best you can afford, and if you can't afford leathers, look for used, something inexpensive online, or previous year suits going cheap. I managed to get a $700 2-piece suit for $250 as they were clearing out the old stuff
