1. My answer is YES
back bodice pattern is 1.5cm longer than the front bodice pattern. In this case should i alter and make them the same length
2. allowance is the extra space you add around the edge of a pattern piece so that it can be sewn together. ... When you are using a block to create a pattern it is much easier to use it without seam allowance and then add seam allowance once the pattern is complete.
