Jeans were very washed--bleached even--and holes in the knees were common (holes anywhere, for that matter). Thing is, jeans always looked clean. There's something that they're doing to jeans now that puts a wash on them that's nothing other than dirt-colored. Jeans did not have this dirty look in the 80's. They were also a tapered leg (trust me, anything that looked vaguely wide at the bottom got you laughed at) and set on the natural waist--or higher. No hip-hugging.
I remember having a pair of jeans that have a brocade-like pattern on the pockets. I thought they were pretty cool. Also had a pair of salt-and-pepper jeans (black, but not solid black) that I was in LOVE with. Oh, and I had this pair of white jeans that had streaks of paint on them that looked like someone had just squirted fabric paint from a bottle all over them. Had a sweat shirt to match that had different colored ribbons sewn on it in random strips, and then it was painted over the same way. Man, what was I thinking? LOL
T-shirts should be extra large and long, and you pull them up on the sides with a T-shirt clip (a round thing that looks like a buckle without a tongue, but a hair scrunchy will do).
Aqua net and bangs. Oh, and a crimper. Remember crimping your hair? Flat, straight hair was very much out. Perms, waves, crimps, curls were all in.
Oh, and I had an outfit that was leggings (totally opaque) with a short skirt attached. Skirts and pants together were in for a little while.
Bangle bracelets. Or multiple watches. Or both. Cheap plastic watches were in. Best to have one in every color so they matched what you were wearing.
Plastic jellies for summertime.
Cut the neckhole out of extra-large sweatshirts. You want it hanging off your shoulder. Also cut the sleeves so that they are short, or remove them all together. You should also cut off the bottom if there is a band, maybe even cut it up so it shows a small amount of belly (over those high-waisted pants, lol). They're supposed to be loose and breezy.
Decorated sweatshirts were also in. Painted, sequined, fabric applique. I had one I loved that was a fabric applique of a rocking horse that had bells sewn onto it so I jingled. Always wore it around Christmas.
