Dress the PopulationWomen's Audrey Spaghetti Strap Midi A-line 3D Floral Dress

Does this dress have good stretch?

I'm a size 8 UK what size would you recommend? thankyou

Would this dress be appropriate for a formal wedding in the fall? And what shoes would look cute with it?

Suggestions for what to use as a bra and/or support that does not show with spaghetti straps?
