You want the best wedding dress for your wedding - a designer dress perhaps but having one done by a designer could take many months and consumes a large part of your wedding budget which could otherwise be used on other things for the wedding.
You only wear the dress for one day and it's unlikely that you will wear it again. After a few years, the dress becomes outdated and your weight will change. Meanwhile, you need to pay for cleaning and storing the dress year after year. Is this all worth it? A better option is to rent your wedding dress. You can rent a designer dress for US$500 or less. You will be able to try it on first to see how it looks on you and the dress will be altered to fit you perfectly.
After your wedding, you just return it. No hassles! Not only will you save a lot of money through renting, you will also minimise wastage which helps protect our environment. Some shops also have a made-to-rent option whereby the dress is made for you according to your design and after your wedding, the shop will use it for rental. This would cost more, may be $1200 and up but is still a lot cheaper than a buying a new one.
