If you are looking for a dorky picture of the early 1970's that shows the typical retro hairstyles and clothing, then take a look at this one. What a beehive she's got there which is actually a decade late but some of the older women back then were still stuck in the 60's, just like we see with some of today's women. Men back then had long side burns as we see here. Older men wore haircuts above the ears and younger guys wore their hair longer and it covered the ears.
This photo has a great example of the wide lapels on sports coats and the wide ties. Wow, that orange shirt was quite the hot color then and that burgundy tie is quite the clasher but matches the leather like piping on the collar. Those were the days.
If you like the bouffant, take a look at the how to.
