I'm your age and your size, I have a real mix of looks but the thing that makes all of them look better for me is my hair being done and a bit of makeup.
My favourite outfits are:
Knitted loungewear with longline gilets over - trainers or boots
V neck thick strapped camis (Roman) with a swingy long cardigan over and straight leg jeans - flats or boots
Midi skirts (pref elasticated waists so I can get them to sit where is most flattering on me) with a skimming t-shirt or roll neck and denim or biker jacket - trainers or boots
Black leather look magic trousers with long line black vest over then a long shacket or unlined faux suede coats - trainers or boots
Knee length swingy tunic dresses with tights and boots
I also wear lots of long smart but loose Made In Italy jumpers over leather or black leggings with boots
Love a shirt dress too, alone or over jeans or leggings, with bottom half undone or all undone with a cami underneath
