Oh OP, I feel your pain - I worked in fashion and was going in to the office everyday pre-pandemic so was always putting the effort in, wearing nice heeled boots, looking a bit smarter… then WFH started, then I got pregnant, then I left the fashion industry and started to WFH permanently and now I’m pregnant again and through those three years, I’ve struggled with my style as my lifestyle has TOTALLY changed. It’s hard! Like lots of PPs have said, get on Pinterest, spend hours on there pinning looks you like AND that are practical for your lifestyle and identify the things that pop up again and again.
also, I follow a stylist on Instagram who is currently doing her top tips on how to create your capsule wardrobe and I think you might find that super useful. Her handle is sam.preston__ and you’ll need to
go on her feed, find the posts with text and start from the oldest one (there are four in total at the mo but it’s an ongoing series).
I’m slightly older than you (35) and a similar build and find that I love straight leg slightly cropped jeans with trainers (Veja / Adidas Sambas / Converse are my go to at the moment), a jumper, a trench coat (or oversized wool coat) and a cross body bag for day-to-day, for feeling a bit put together but still comfortable enough to chase after the toddler. When it warms up I like a midi dress with trainers. I’m not one for print or colour (I wear a lot of black and neutrals) so any specific suggestions I have probably won’t be to your taste but definitely have a look at Pinterest, find people whose style you like on Instagram, build a moodboard of what you like and go from there.
good luck!!
