I want them to be able to pick their own shoes or wear ones they already own, but I would like them to be in the same color family. The colors we're using in the ceremony are light pink and medium grey. They'll be carrying clutches in different shades/patterns of pink.
Which do you think would look better with this dress?

(I don't want/expect them to buy these specific shoes below, just an example of the colors.)
Beige/taupe shoes:

Light grey shoes:
