i took my wedding dres in to get hemed and it was very lacey and had alot of beadwork. The owner did an excellent job of making the alterations. She had to hand pick the beads, alter the hem line, then hand sew the beads back on. it was a complicated process but the dress looked perfect. i also felt the price was reasonable. the only con i can think of is she is a busy lady and so it does take a few days to get things back.
Pros: excell seamstress
Cons: takes some time
