If you are into 80s pop culture, there is probably a personal reason for what you collect or what you may want to collect. There were two main music trends in the 80s of note. There was the hair metal of the late 80s and then the electronic, techno-pop of the early 80s. There was other music, especially pop music, that was big then, but the before mentioned created the biggest buzz. Most people liked one or the other, but usually not both. You can go out and find old albums and other band collectibles of your favorites if you remember either of these and want to connect with your youth.
Another collectible from 80s pop culture could be clothing accessories and jewelry. There were a lot of trends in these areas that died off and may be coming back around now. The colors were bright neons like pink and green and some pastels. The belts were hung off the hips. They started small and ended up being very oversized and vibrant. Colored pearls were popular for a while, along with wearing tons of bracelets of all sizes and colors all at once on each arm. Earrings and hair items were also large, colorful, and sometimes came in geometric shapes.
Toys are huge in 80s pop culture collectables. There are too many different toys that were popular to name them all, but you probably had your most favorites. You can find many of them online, though they are going to cost more now than they did then. Just a few of the most loved collectables are Rainbow Bright, My Little Pony, Transformers, He-Man, Weeble Wobbles, Strawberry Shortcake and friends, and various trendy toys that you may not even remember until you see them.
80s pop culture collectables can be anything you want them to be. If you remember something fondly, chances are good that you can look online and find what you seek. You may even want to see what you can find in consignment stores that deal in older toys and items, and you can even see what your parents may have saved in their attic. There are newer versions of these older toys on the market as well, though to be honest, they are not the same as the original. However, you may smile to see your children playing with something you use to play with, even if it is a newer and different version than you remember.
