70s outfit for a M-L woman (South Jan Jose, 95118)

I'm going to a 70s event and I could use your help. I'm looking to put together a fun 70s style outfit. I'd prefer disco style, but open to other ideas from this era. The event is in SF, so I prefer pants over a dress, due to the cold weather. I'm thinking bell bottoms and maybe a top with flared sleeves, or something shiny? I'd like wear a headband too. Boots would be cool too if they were comfortable. I wear a women's M-L (size 8-12 pants, M-L top) and a size 8.5 - 9 shoe. Does anyone have anything that would fit the theme (and ME) that I can have or borrow? If so, please DM me.
