Twist Knot

People say they are getting tired of all the ruffles. I'm not sure I disagree. (How's that for double negatively vague?)

But what I do love (and can be clear on) is the twist knot.

I already own:

TJ Maxx

(Anthropologie)
(I have this in navy + white but love this color combo as well.)

Just how many twist knots should one person own? For example, if I was to add these to my closet, would that be too many?

(Garnet Hill)

(Banana Republic)

The correct answer is: depends on how much they are marked down.
