Continuity: At the end of the movie, the Commitments article states that there were 27 bridesmaids after it is stated that all the women Jane was a bridesmaid for were bridesmaids at her wedding. If that's the case, then there were really 29 bridesmaids, since in addition to the 27 bridesmaids from previous weddings, her unmarried sister and best friend were also bridesmaids.
