IKEA is great for anyone starting out, furnishing a rental property or just not sure what they want. It may not be the best "last for ever" quality, but it does the job, looks reasonable and can be mixed with other pieces over time. It tends to be good quality for the money. Tastes change over time and while my parents invested as much as they could in the furniture they bought, as they wanted it to last a lifetime, I prefer to think I will be able to change and update easily in the future. I spent a fortune on some furniture a few years ago, that I would love to replace now. We didn´t have a nearby IKEA at the time unfortunately.

Slopes and awkward spaces are not an issue with our system :) www.nordikka.co

I love wumi's design too. If that gives you enough hanging/shelf space I'd def recommend the dressing table under the window in a right angle arrangement. I've got a, very similar sized room I've changed into a dressing room. Until recently I had the dressing table on the other wall running parallel with the wardrobes, thinking that was the best arrangement. But having to use the room for an office as well I moved the dressing table/desk under the window (I can't blur the background on my video calls and have open wardrobes) Its made a huge difference and given me so much more floor space in a very small room.

I agree with all of the above comments. Ikea is incredibly good value for money and they do invest in design. The carcasses go lower than standard ones, so you get more room inside the cupboards and they appear lower to the floor which looks good. As they are deeper, you need to get non standard worktops so this is worth thinking about. They hang on rails on the wall and then the front legs provide stability, my carpenter was very impressed. The only negative issue I found was that (certainly at the time) we had to use one of their own integrated dishwashers as other brands didn't fit. As this is the case, go for the best quality dishwasher they do, not the cheapest. I would get a good carpenter to fit it and expect it to take quite some time. There are lots of companies doing Ikea hacks such as making doors form formica ply etc. Also some good ideas on instagram.
