Thank you. I mean 'plain' without having colored or patterned shape on the clothing. Is 'plain' commonly used?
Not usually. If there's no plaid or check or pattern or stripe, it's usually not even mentioned.
Braids can be one or more plaited strands of hair and can be wound around the head or worn any way.
Pig tails are usually on small girls and consist of two braids, one hanging down on each side of the head, and they usually have a ribbon tied around the end.
All the expressions you provided are correct. Here's a breakdown and explanation for each of them:
1. She has a perm. - "Perm" is short for "permanent wave," which is a hairstyle that involves chemically or mechanically adding curls or waves to the hair. So, "She has a perm" means that her hair has been treated to have permanent waves.
2. She has a polka dot dress. - This means that the dress she is wearing has a pattern of small, round dots evenly distributed across the fabric.
3. The girl has pigtails / braids / plaits. - Pigtails, braids, and plaits are all hairstyles created by dividing the hair into two sections and tying them separately. The difference lies in the method of tying. Pigtails are simply two ponytails tied at the sides, while braids and plaits involve weaving or intertwining the hair strands. In general, "braids" is often used in American English, while "plaits" is more commonly used in British English.
4. Her older sister is wearing a pink plain dress. - This means that her sister is wearing a dress that is pink in color and does not have any patterns or designs on it. It is a solid, plain color.
5. Her brother is wearing a horizontally striped sweater. - This means that her brother is wearing a sweater with stripes that run horizontally across the fabric, parallel to the ground.
6. She is wearing a vertically orange plain skirt. - This means that she is wearing a skirt that is orange in color and does not have any patterns or designs on it. Additionally, the skirt has vertical lines or texture that run from the waist to the hem.
7. The girl is wearing a ribbon on top of her hair. - This means that the girl has tied a ribbon above or on top of her hair, possibly as an accessory or decoration.
8. The girl having a ponytail is wearing a patterned dress. - This means that the girl, who has her hair tied in a ponytail, is wearing a dress that has a pattern or design on it.
9. The wife is wearing a pink polka dot dress. - Similar to the previous statement, this means that the wife is wearing a dress that is pink in color and has a pattern of small, round dots.
10. Her mother has long wavy black hair. - This means that her mother's hair is long in length, has waves or curls naturally, and is black in color.
