It's Friday and I Need an Opinion

I'm having a decision-dilemma.

I can't decide which shoes to wear for Erin's wedding.

I'm hoping y'all can help me choose!  

I'd prefer to just wear my flip-flops (or - better yet - no shoes at all!!!), but I think I'm going to have to go with mother-of-the-bride respectable for this one, and put on Real Shoes.

Here's my dress. . .

After shopping (in stores and online), I remain uninspired with my shoe options, but I've narrowed it down to two pair.

What do you think?

Disco feet? 

(These somewhat sparkly silver sandals are comfortable and - as a surprise bonus - they do not highlight my extreme flip-flop tan lines.)

OR . . . 

Neutral putty peep-toes?

(Also comfortable and nearly invisible - but my god . . . that flip-flop tan line is rather extreme.)

OR . . . 

Should I keep shopping?  (And, if so, for WHAT . . . exactly?)

What do you think?  Opinions, please!  Help me decide. . .
