Hello 👋 Nanafizz, there are some nice floaty dresses in the supermarkets, also Peacocks and Bonmarche, very reasonable.
I use Ambre Solaire aftersun on my legs, it has tan enhancer and gives my legs a nice colour, very easy to apply, just like body lotion. Sometimes, like Poppy red, I wear crop leggings with knee length dresses. My feet aren't my best features so I wear nice comfy Skechers Bobs espadrilles style sandals, sling backs, covered toe. I'll try to post some photos, sorry I can't do links.
When I wore a smart dress and jacket recently ( for DH's funeral) I wore Snag tights, they come in various deniers and sizes, and really hide varicose veins and blemishes. I recommend a wee look at their website.
Wishing you well whatever you decide.
