HELP - need a "60s-inspired" outfit for a party

[fluffles]

I don't buy many clothes so i've no idea what's in the shops. is there anything around in the shops for autumn that is 60s-inspired?

i've got a 60s style party in October and don't want to look daft or buy something i'll never wear again but do want to make a nod towards the theme.

have short legs and am hourglass so nothing twiggy-like

also have curly hair so it's going to be tricky to make that look 60s-like too but i guess i'll try giant velcro rollers.

i have some great knee-high black boots already so something to wear with them might work.
