Natural hair colours (so no in your face dye jobs where it’s obvious your hair didn’t come out of your head that colour). Glossy, unfussy haircut/style.
Short, neat, clean nails.
No visible tattoos or piercings.
Well cut, made to last clothing. Often in natural fibres. Good basics like a beautiful coat, great footwear.
Never showing your underwear in public (I.e when you bend or deliberately as outerwear).
No fake tan.
Natural looking eyebrows.
Simple but expensive jewellery.
Good posture.
Good teeth.
Excellent manners.
Good conversationalists who can put anyone at ease.
Being self disciplined and knowing how to do things in moderation (ie alcohol, food, having a structure to one’s day)
I can imagine to some it all sounds very boring!
