Before And After Pics Of A Brazilian Wax Wedding At 2pm, What To Wear?

Wedding at 2pm, what to wear? - before and after pics of a brazilian wax

Hello getting my sister married this coming Friday, will be 2 hours, then go to dinner and then go to a party at the Rugby Club. I'm Brazilian and I have never been to a wedding UK before, so I'm really lost, the most important question is what to wear? I am over weight and wear no clothes, please, help me suggest what they wear (with photos if possbile)

Thanks
