I’m a polished person! I’m not necessarily super smartly dressed or anything like that, but I am always told I look “well put together”. I don’t have children so that probably helps, but here are my tips:
Hair - mine is in a very sharp bob, and is trimmed every five weeks. I always book my next appointment as I leave. I have an excellent hairdresser which I think makes a huge difference, but I am also very lucky that I don’t pay him and instead do the salon’s social media in exchange
Eyebrows - waxed every three weeks, appointments are scheduled in until about October at the moment
Clothes - buy the best I can, often second hand. Today I was in Levi’s balloon jeans, a lovely orange sweatshirt from Arket, and Birkenstock clogs. All of those items came from Depop. I always pick my outfit the night before and hang it in the bathroom, complete with bra/knickers, vest for underneath. I know MN hates this but I iron everything. We have a very fluffy cat and there is a lint roller in every room, plus one by the front door. I wear trainers a lot, but if I am in boots or shoes I make sure they are polished/repaired regularly. If something looks scruffy or doesn’t fit, off it goes
Nails - do them myself, every three days
Makeup - I always wear red lipstick even if nothing else. It’s my “signature look”. I tint my own brows and lashes at home so if my skin looks okay I can get away with lips, lash curlers, brow gel, done.
That turned into a book, but maybe there is something useful, OP. I bet you look great though!
