Nina Ricci Vintage Pattern Splurge

I somehow stumbled across this 1970 Vogue Paris Originals pattern while perusing current Nina Ricci pieces. 

The jacket is unremarkable, but isn't the dress fabulous?! The fitted bodice and long sleeves, the exaggerated skirt, the center pleat detailing... I just had to have this dress pattern! Even though it was $25.
