Does any one have experience with...

Tiana • I'm interested in nice clothes & living a wonderful life. Very much in love with a fantastic man. 19. University Student
40's style partner dancing?! My lovely boyfriend just surprised me, telling me he's signed us up for a lesson for our usual Friday date night! Which will be delightful but it would be awesome if I had some tips because I'm not necessarily the most graceful or most experienced in the dance department (granted neither is he but I'd love to be at least a little bit prepared) 
Any tips would be wonderful!! Thanks :)
