One of the biggest trends in the design world today is the retro style inspired looks that you can find in logos, stationary and lately I've ran into quite a few wedding invitations in this style.
A lot of them have this sort of art nouveau feel to them, mixed with bold contemporary fonts and clean cut shapes and lines, letterpress is also a recurrent method of print. It's always nice to see great design to commemorate such a special date, and what better way to invite your guests than through a beautifully constructed and personalized card. Beauty is all about the details, and that seems to be the common factor in this trend with unique isotypes, patterns, and mixed fonts.
Here are some great examples, enjoy!
