The clogs @XiCi posted would work well imo, I've some Clarke's ones v similar & they're comfy & literally work with everything.
Don't mean to be a cow but denim jackets are not only uncomfortable & no use if the temperature drops but their stock has fallen considerably since the fashion set dubbed it 'cheugy' which is basically the opposite to trendy!
I'm not a fan of big white trainers either OP! So inelegant. Leave it to the teens!
