The point of the dressing room is that you don't have to go through the bedroom twice and potentially wake your partner, which you actually want to avoid with such a dressing room. In addition, the closets can be arranged as a "two-liner" without a corner (which I find very impractical), and the room could then also be a bit narrower (2x60cm for closets plus 140cm (or even 120cm) in the middle makes 2.6m, which I would really consider sufficient). The 38cm can be added to the children's room as a nice niche for shelves or a wardrobe if 120cm in the "dressing room middle" is enough.
