Finding the right wedding dress can often seem like a daunting task, when really it should be one of the most exciting aspects of the wedding... and it can be... just make sure you are prepared before you start looking...
Firstly... have a price in mind. If you know how much you are willing and able to spend on a dress then there isn't much point trying on dresses above what you can afford as you're potentially setting yourself up for heartbreak if you find one you love but can't afford... instead try on dresses within your price range... you will be surprised by how many amazingly beautiful gowns you can find in any budget.
If buying online make sure its with a company that comes recommended by more than one person and keep in mind the cost of alterations, taxes and shipping fees.
Make sure you give yourself enough time... I know many brides want to loose weight or tone up before their wedding day but you should also be aware that leaving dress shopping to the last minute in the hope that you loose those few kgs might mean that the dress you love... wont be made or delivered in time... so start shopping early... even 10 months early... you might take a while to find your style and leaving things to the last minute can become stressful.
Trust the salesperson! If you go into a bridal shop you need to trust the salesperson... they have a LOT more experience in dressing brides than you do... what you think might look hidious on the coathanger may look amazing on...
Don't rush into buying... I have heard of several brides ending up with 4 or more dresses because they kept changing their mind... so if you find a dress you love... dont rush into buying it. Take a bridesmaid or your mum along for a second opinion. Leave it a few weeks and then re try on the dress you fell in love with... and if you still love it... and it makes you feel amazing... then buy it.
And my final peice of advice... it is YOUR day... no one elses. If you want to wear a black wedding dress... then wear one! If you want a floral dress... go for it! If you have always wanted to wear a full "church" wedding gown but are now having a backyard wedding... who cares... it is YOUR day and you should wear what YOU want.
