I am so happy to hear! :) Absolutely, to add length after printing and cutting out the pattern glue more paper at the bottom of the robe's hem and continue drawing the side seam line until it reaches your desired length. In theory the best would be to do this before you buy the fabric and then recalculate on your own how much fabric you need. But for a quick calculation head to the shopping list photo, take the amount needed for your size. Then measure starting from ~5cm (2") above your knee to the length you want. And then multiply this amount with 2. For example if you want it to go to the floor, you will need to add around 60cm, thus buy 120cm more fabric :) Let me know if I should better explain some parts ❤

Yes, just skip the sleeves :) However, you should hem the opening somehow. Super easy option would be to neaten the edge around the armhole and then edgestitch 1cm (1/2") or you could use a bias binding. Let me know if you have any questions 🤗
