Depends on what type of clothing you feel comfortable in wearing (material / style / colour). It could be a good quality good snit trousers with a jumper and cardigan. It could be a knit dress with knit cardigan

Isn’t the mother of the bride meant to wear blue? Mmmm. Regardless wear something that is comfortable. A dress with a shawl is lovely.

A light knit suit might be good. Layers can work too, especially if you’re going to be both outside and inside. Choose a color that suits you, and you’ll feel good.

May be long sleeve dress with good fabric.

If comfortable going to a store a stylist can assist with finding an outfit that meets requirements.

Maybe opt for a longer length thick skirt and team it with a pretty blouse and a warm shawl. I am sure your daughter understands your concerns and appreciates your need to look after your health.

A comfortable outfit with layers is always a good way to go. Wraps are pretty and warm and look quite beautiful with the right outfit. Wear a style and colour that you like and feel comfortable wearing.

Maybe a pant suit? But nothing in white!
