It's super early on the morning of my daughter's wedding and I can't sleep, so posting for advice.

Does this work?

The weather here in South Africa is unseasonably warm for late autumn/early winter. It reached 29'C yesterday! But became chilly enough that I needed sleeves in the evening and turned on the heat overnight.

Today is forecast a high of 26, and already starting to cool at 3 when the wedding officially starts.

I've dreamed of turning this ball dress (from my youngest daughter's wedding) to a Carolina Herrera look with white shirt and ball skirt. I contemplated wrapping it and belting it somehow (I brought some tartan ribbon) but that doesn't allow for de-layering should I get too hot. Does folded under and knotted this way work?

Cuffs flipped as in 1/2, or buttoned as in 3?

I have a blue gemstone bracelet I plan to wear, but will need help to do it up, so not modelled.

Expecting cold weather, I thought I'd wear a navy cashmere crewneck as my top half. So my hair down and loose would have provided the bright contrast near my face. The bride is setting me up with her hair and makeup crew. Any suggestions what I should ask for? I don't find updos to be flattering on me.

Any thoughts?

PS notice the thatched roof/ceiling in this cottage on a wine farm?
