I’m with everyone else saying to go for what YOU like and not what is rare/your SA tells you. Personally, I would take the Celeste K25. I think the color is very unique and hard to find from other brands. I am biased since I have a mini K in Celeste myself, but at the same time I think the K25 is a better bag size in general (minis can be a bit restrictive and are a very specific look). Therefore, I probably wouldn’t gravitate towards the Mini K kn Bleu royale. I feel like the size makes it very out there, but the color is a bit too «plain» for the bag in a way. If that makes sense?
I also feel like anemone is a very specific look and color, which I think you really have to love that particular shade (I do not but if you do then absolutely go for it). So that’s my take on things!
