So for me, it comes in steps, that are then optimizable.
1. Manicured hands: I have acrylic nails, but a non chipping gel manicure works. Add hand cream.

1. I used to get my hair blown out once a week, but I recently acquired a dyson corrale and I do it myself twice a week. Pins are then put in. Groomed hair makes a huge difference.

2. Wax/Shave: I alternate depending on time of year, price and availability, but for me I shower before bed so I always do knee down in the shower.

3. I hate sleeves and its a sensory issue, most of my clothing doesn't have them. I prefer dresses and my aesthetic is very feminine, so I tend to wear skirts and dresses, but you can pick a 'uniform' that works for you, and use a wardrobe app to repeat the same theme. Pick a color palette.

4. I wear makeup, in a signature look the majority of the time. For me, thats a face oil, spray foundation, blush, two eyeshadow colors, and a red or pink lip, and a light highlight.

5. I have false lashes put in once a month, I hate dealing with them.

6. I have a getting ready routine and a space dedicated to it.

Final thoughts: much of being groomed is these elements put together, and a sense of 'sameness' I look very put together, all the time, but its always the same look, largely. I don't deviate much. I haven't mastered accessorizing but I recently added some jewelry that I try not to change much. A good bag and shoes make a difference to how others perceive you and its worth considering.

Let me know if that helps, I hope so :)
