Antje, I will get to the booties in a moment, but first, I meant to comment in your last thread about how fabulous you look in that dress in #6. Just stunning on you!
As for the booties, I agree with those who say you wear them very well and they seem to fit in with your style. You have terrific legs and these are lovely, slightly edgy, yet still comfortable-looking shoes.
Having said that, I absolutely understand your reservations. I feel similarly for myself. Not having super long legs, I worry about the stump factor of a high vamp, and even if that is not what others see, that is what I see (on myself, I mean). So for me it is very tricky and the hose and bootie must be the same colour or I just won't feel comfortable.
Here, the taupe is absolutely beautiful, but with your delicate ankle and that horizontal line, there is a sense of cut-off. It is slight, it does not make them look bad (to my eye) but it is there.
On the other hand, these bookend your hair beautifully, much better than a true beige probably would. And I think they are an incredibly versatile colour that sort of blends with whatever else you might be wearing; they work with cool tones but also with warms and look very sophisticated.
So...it's a tough call. I would hang onto them and wear them around the house for a few days if you can, to try to puzzle it through. And good luck!
