I can send you a little bit of mine if you want to try a bit before buying.
I'm a generally allergicy itchy sort of person and my skin gets very itchy when I'm tense, so I scratch, and even a light scratching will result in huge vivid red wheals appearing within a minute and lasting for half an hour or so. Sometimes I scratch an itch on my face and then wonder why people are asking me what I've done to my face, not realising I look like I've had 20 lashes! I take a daily antihistamine, which helps to keep it under control, but it doesn't bother me unduly. I think that although the appearance of the wheals can be quite spectacular, I don't really suffer it in the way that some people do and it doesn't make me miserable.
My annual summer (well, March - September) allergic conjunctivitis - left eye only - on the other hand, drives me crazy and this year I've been so fed up with it I went to see a homeopath and it seems to be working. I've been able to tolerate my contact lenses on 4 days in the last week. I don't think I've been able to wear contact lenses between March - September at all in the last 4 or 5 years so I'm very impressed.
ETA: oh, fabrics. I do better with natural fabrics, wool makes me itch like mad, and I don't like tight cuffs. Tight cuffs round my wrists marks them very badly so I go for wider sleeves with looser cuffs.
