As the 19th century approached, Paul Poiret gave fashion a new dimension with the bold prints and bright oriental colors. Way back then some of the prints were worn during the World War II with bright colors and multiple patterns through the 1950's.
As the fashion designer said once: "My prints are ornamental designs worked in continuous motion; how ever there are placed there is rythm".
Later in the 1960's, the young generation adopted this kind of look. You could see loud floral and colored stripes and other sorts of prints.
Let's not forget by the end of the decade the hippie movement had a huge impact into this kind of dressing code. Going from graphic patterns and tie-dye. Christian Lacroix immersed in it. A lot of fashion designers has been influenced by runaways shows but most all in the streets.
Spring is ideal for this type dressing so go for it!
