Hi OP,
I’m about your age and was a SAHM who worked part time until last year when I went full time. So I can relate. I love fashion and style and dressing well. My DM was always under stylish and her motto, which I follow, was ‘never save it for best’.
I shower ever morning and do a full body scrub with a mitt, then I lather on body lotion. I wear tinted moisturiser when I work from home, and at weekends, with mascara and eyebrow gel and concealer. That’s it.
When I work in the office i swap to the Sculpted by Aimee cushion foundation which I lived from the moment I tried it on in her store. Takes 1 minute with a brush but is a fine mist liquid in a cushion (go try it - I can’t explain).
You need more up to date jeans or trousers. I update my jeans and trousers regularly otherwise you end up wearing something that looks slightly off. For comfort try barrel leg - and S have loads in jeans and in cargo pants. Pair with long sleeve t shirt; then add a merino wool jumper in a colour that you love and then but more of this outfit in 2 more colour combinations that all work together.
Add Chelsea boots for day to day - I have thick soled Chelsea boot wellies that I wear all winter as I walk my dog daily. Inside change to Uggs ur fluffy socks or whatever is warm and comfy for you (my house is a shoes off house(.
To dress this up add jewellery/a nice cashmere scarf/ a lovely coat - I have a stylish rain coat for walking the dog and some lovely wool coats and a trench coat. Try on some in store and buy similar on Vinted. Sweaty Betty are great for rain clothing and as are rains. Buy them oversized.
For going out, try heels - kitten heel boots or shoes: swap the long sleeved t shirt for a silky cami under the merino sweater; or buy a silky blouse in your favorite colour - loads in M and S - and wear this.
To get more ideas, find people who look a bit like you would like to look and follow them on Instagram.
Here are some stylish women I follow for inspiration-not actually lists of shops that they buy from although they are here too
