Mixing different prints and patterns together - Stripes and polka dots are probably the easiest way to do it...
...or buy a dress with mixed prints -
Bright colors -
Long flowing skirts and dresses -
Big statement necklaces -
70's retro -
...as well as 40's, 50's and 80's retro. Almost any decade will do. Vintage is "in".
So, which trend are you going to wear this Fall?
