I saved soooo much and still got the best!
They are not cheap, but quality of the work and their products are worth every penny!! One thing that isn't mentioned by any bride, it seems (and they themselves keep very low key too) is that they offer 20% off a short period each year on their web site only, which become a good saving for any bride. After visiting a tailor shop, I personally was determined to use MDAT for my alterations and was willing to pay what ever it would take, but I just got lucky when I went to the website while they were offering that 20% off.
On my wedding dress alterations, belt, and veil I saved a total of $480, which brought the cost of alterations about the same as what the low-skilled tailor shop quoted me, except that they did not even want to touch the bust that looked funny on me!! If you have enough time to your wedding you may want to check their site very often and see how it works for you, but DO NOT miss the opportunity of having a perfect fit in hope of saving a couple of hundreds!!
Good luck everyone!
