58, so near your age, OP. After years of not being interested in jeans, I have bought a pair from Zara, https://www.zara.com/uk/en/trf-cropped-flare-high-waist-jeans-p04806018.html?v1=352754146
to go with an oversized stripe shirt, also from Zara. https://www.zara.com/uk/en/oversize-striped-oxford-shirt-p02298051.html
I will wear both items with other things, but I'm basically copying a look from a 'Parisian' YouTube channel. You do a French tuck with the huge shirt, you flounce about in your chunky sandals and your raffia bag and shades, yada yada.
Have also bought, from Massimo Dutti, a pair of white linen trousers and the same pair in black. Also a cream cotton knit floppy, boat-neck jumper. Massimo Dutti have an awesome collection currently, but a shit website, so sorry, can't load the pics.
Might be tempted by another pair of jeans, high-waist, straight leg, blue wash. I need a belt (Cos has the one I like), maybe a T-shirt or two, and I'm tempted by a Roxane Baines dress.
