Style and beauty experts, I trust your judgement as always. I’ve bought this skirt but I’m wavering on the length. I’m 47, about 5 4, a curvy toned size 10 ( which is apparently a large in Zara 😡🤔). I was thinking thick black tights/ fine knit jumper or a slouchy jersey too/ ankle boots. But am I kidding myself ? I know I need better undies to flatten my tum.
