|When cutting out a master pattern or sloper, its a good idea to have compared some measurements - across chest, across back, bust, depth of BP, side seam length to a comfy armhole, and checking the pattern against them. Measurements don't help with all issues though, and one area where its useful to have extra seam allowance to play with is on the shoulder seam. So my tip is to allow plenty here. This lets you replan the shoulder seam when you try it on, moving the line to a more flattering position if need be, by taking off or some at the back shoulder and adding it to the front at SP or NP or both for example. Its not uncommon to need to move the line half an inch in one of these places, and if you only have five eighths seam allowance its difficult.
