contemporary is all about simplicity & sophistication... clean lines, modern colours & definitely all about being chic.
elements which could be considered contemporary are:
1} bright, bold colours mixed together, such as apple green & chocolate brown
2} stationery could feature emblems or motifs rather than lace & ribbons
3} dramatic flowers such as cala lilies with their clean lines & dramatic long stalks fit well within the modern theme.
4} plan on an unusual shaped cake rather than the traditional round or square
