In a recent discussion re wedding dress alterations, several people, myself included, recommended Pam Harris 204-573-8298 - she lives in the country near Chater. If you call her she can give you exact directions.
Here is the link to the previous discussion, might give you a couple more options but Pam does come highly recommended by several people.
