What do you think of my color and decor combinations?

My first bit of advice is remember this is you's and your fiance's big day, you should be considerate of different opinions but your the one that has to live with the final look, feel and cost of the wedding. That being said I have a couple suggestions, first of all a cheap way to avoid plastic but not splurge on pro linens is go to a local craft store and purchase inexpensive cloth and sew your own, if you use square table cloths its super easy! Secondly I would suggest using white gerberas for the bridesmades with little splashes of color like the wraps on the handles or colored sweetheart roses, it will help to make the dresses and the flowers pop instead of blending together. Putting the flowergirl in white will help her stand outand feel special, doing so will help her feel important and she will try her best for the walk down the aisle. On the jewelry depending on the dress styles pho colored pearls could be a nice touch, or going with clic silver colored jewelry would stop everything from being to matchy-matchy, and for the bride a little glitter doesn't hurt, if you go to antique/junk shops you can find CZ, crystal or rhinstone jewelry pretty cheap, or browse the internet or shops like Claire's or Icing have cute stuff for good prices. I love clic frech tips for weddings and you can make the tips any color you like. A good rule to follow: elegant and timeless is the way to go with everything. Lastly remember the pictures taken at you wedding will be around in 20 years, so you don't want to look back and say "wow I can't believe I went with fads and trends for my wedding!"
