Packing cubes have really helped me. I tend to do them one of 2 ways:
Categories - knickers in 1, socks and bras in another, tops (rolled) in another and trousers laid out on top;
Outfits: a full days outfit each in 2, and then the other 2 being the extra tops/knickers/socks for 1 combo of trousers in 1 and the extras for my other trousers combo in the second.
Wear my walking shoes, jewellery in a pouch (and chains in individual packs inside that to avoid tangles) sitting inside my other pair of shoes. Possibly also my toothbrush (in plastic holder) and hairbrush stuck into other shoe.
Clear zipped pouch for my liquids - from Boots (middle size of set of 3) years ago - and small sizes of the things I need. I keep toothpaste samples from dentist, gift sized toiletries from larger purchases, and use a mix of 30/50/100ml bottles from Muji for shower gel, shampoo, conditioner, etc. But all is ready To easily pull out for airport security.
Smallest pouch of that set holds my travel makeup brushes (short handle set), powders (for after foundation, blush, eyeshadow); powder exfoliator, small facial sponge, plastic shower cap, couple of hair clips, cotton buds, toothfloss sticks, nail file etc. Shouldn't be asked for it, but if they do, everything is visible. (I have a couple of very small ziploc in there, both from Muji, to hold my makeup brushes and the other small bits like cotton buds, couple of cotton pads, toothflosser, nail file, tweezers etc).
I tend to wear 1 trousers that has at least 2 tops to go with it. And pack a second trousers (or 2 pairs of shorts perhaps) which also has 2 sets of tops. Usually bring 1 dress. Throw a lightweight hoodie into my handbag or over my shoulders. There's a scarf that can go with a couple of the outfits (for cooler evenings/days but also inc as I need to cover head or shoulders for some reason). 1 pair pj tops but usually 2 bottoms (I sweat at night).
If I am going a long time (more than 4-5 days), I add a bottle of handwash or use the hotel shower gel to give some clothes a quick wash in sink and hang to dry in bathroom to reuse - or sometimes there will be a washing machine in the hotel/accommodation that can be used. And if it will be a long one, I will use the hotel shower gel or go buy one locally on arrival.
I have just come on a 9 day trip and all my things fitted into my carryon.
