I took my Mother's wedding dress in to be radically altered for my own wedding. Janette's prices are reasonable, but she had my dress from February through August... and I asked her to have it completed by July. Not cool. I also have serious doubts about the level of her craftsmanship and professionalism. At one of my fittings, a waistline which we had pinned (straight) previously, was sewn completely on a diagonal. (Ummm? this is my WEDDING DRESS, could you bust out a measuring tape or something?!) So, needless to say, I have lost most of my confidence in her ability to finish anything nicely. Further, she told me to wait until after the fittings were completed before I got my dress cleaned. So, I did. But after I spoke with several restoration cleaners, I was informed by them that because of potential shrinkage issues, I should have had the dress cleaned BEFORE I had the alterations done.
I have a "Plan B" in place. THANKFULLY. (IE: getting my dress cleaned after my alterations by Janette are done and then going to another dressmaker to clean-up whatever messes she made.)
My suggestion? If you are using Janette for very simple things like hems or taking something in, she's worth it. But, if you need anything special altered and you need someone talented who pays attention to details- don't use her!
