Wedding wear question?

I have a wedding to go to in August. The people who will be there are my hubby's family members who haven't seen me in a while. I have changed a lot since they did. I use to weigh 260 lbs, had grey hair and walked with a cane. I now have lost a LOT of weight, have dark red hair (my original color) and am a hobby runner and a weight lifter, and had my teeth capped. I look very good for my age now (50). I need suggestions on the type of evening wear I should purchase for this wedding. It is going to be very hot and the little country church where the ceremony is isn't air conditioned. What kind of fabric is the best to wear under the heat situation that I am going to be in? Also I have excess skin on my arms and legs and need to comoflauge as much of this as possible. Any suggestions would be appreciated. Thanks.

Ah, Prairie Crone with Red Hair, your 'original colour'.

What a marvel ! How long is your Glorious Mane ? On its own, it is a thing of its own. Don't wear Black: not good for a Wedding in August & methinks it will not reveal enough your 'originality' and I'm certain your unique sense of Humour.

I am not one for Flattery - check my Q/A's.

Cover your legs, so that you can forget about them.

DON'T COMPROMISE ON SHOES. I can run run in High heels, how are your feet ? If acceptable: Play all the Way - emphasis on Colour. Experiment beforehand with a Professional pedicure: if you look after your feet from now on, they will return the favour.( promise: hope to die).
