I am quite stunned by these other bad reviews. I didn't buy my dress at Matinas, but they performed my alterations and I also bought my accessories (veil, belt, and hair piece) with them and I couldn't have been happier.
I purchased my wedding gown on-line (monique lhuillier) for an amazing price, but it had a weird "couture" neckline (i had a love-hate relationship with it until I realized it wasn't good for my body type) and was too big. The dress was of course all intricate lace as well as horse-hair at the neckline and I was wondering how anyone would be able to make it into the dress I envisioned (we actually highly considered trying to sell it ourselves and just buying a new dress from scratch). But Mira who does alterations was able to create the PERFECT dress for me -- the neckline, bodice, and overall fit was amazing. She listened to all of our concerns (my mom and I -- we often had differing opinions!) and was extremely flexible considering I changed my mind a BUNCH of times. She also worked fast and efficiently, working with my hectic schedule. The prices for the alterations were very, very reasonable. Mira is basically a miracle worker -- it really could have ended up as a disaster in anyone else's hands. I don't know what we would've done without her.
The veil, belt, and hair piece were also beautiful accessories and of very high quality. The veil in particular is stunning.
Julie the owner is also very nice, professional, and flexible. Even though we only did our alterations there, she always made us feel like VIP customers. If I didn't get my dress online, I would've probably have gotten my dress there!
