I would read anything and everything in my teens.
Such nostalgia - I got Bunty and then Jackie and then Just 17 and Mizz - my sister got the Beano. Bunty was delivered to my dad's each week and I would get it when I went round there for one day every weekend, as my parents were divorced. I also read my sister's Beano for quite a while.
I won a short story competition in Mizz later on. Then I bought Cosmopolitan, Company, Red, Marie Claire etc for years, but only get very occasional copies now - I still succumb to music and baby magazines occasionally though.
MorrisZapp, I read Just 17 when it first came out and I think it was quite good then, it went really downhill later. The original editorial policy included not taking advertising for diet products, I think, and the agony aunt column was trying to be a bit more realistic about the problems faced by young teenagers. I think for a while Just 17 and Mizz were real alternatives to Bunty/Jackie etc. I also prefer those girls' comics to the preteen magazines that came later such as Sugar (yuk). I do remember Minx and it was quite fun.
I also read Spare Rib and Shocking Pink, and some books aimed at giving teenagers a feminist consciousness. One of the Shocking Pink collective died in her early 40s of cancer a year or so ago, and I found a novel by her in the library in which the heroine manages to recover from heroin addiction while continuing with voluntary work on a feminist magazine collective. Presumably the mag part was autobiographical, I don't know if the drug bit was too.
I don't remember Fab in comic/magazine form but had at least one of their annuals though can't remember the details.
SolidGoldBrass, it might be worth asking on your local Freecycle or something if anyone still has copies they don't want before they get the recycling collected.
