I didn't do a deb or prom thing but we did have Boatrace Ball for years 10-12 at our school. I went in year 10 and year 12, not year 11 though for some reason

Anyway year 10 I wore a silver snakeskin sort of texture fitted halter-neck dress (ok it sounds awful but it was 1987 and compared to the pouffee taffeta numbers it was up against, it looked hot!) and I went with a male friend. Had a great night, danced lots and made the guy who asked me to go and then un-asked me to take someone else totally jealous as I looked way hotter than the girl he ditched me for

Year 12 I went with another male friend (gay) and we also had an awesome night. I wore a black fitted, just above knee length dress with a deep V in the back which was my aunties from the 60's. Again a great dress for 1989 when you look at what he others wore. I think I probably got drunk before we went because I don't remember that much of it
