Hi.

I want to make sure if the underlined parts are correct below.

It is a clear sunny day in the mountains; A young child is skiing on snow covered slopes. She is accompanied by a man and woman, who are also skiing and carefully watching her.

She is wearing a colourful outfit which includes: a light-blue jacket, red pants with a black stripe on each side, blue gloves and shoes, a white muffler, orange ski glasses, a dark blue cap, and she is holding pink ski sticks. Her ski's also are pink.


I wonder if the underlined parts have typo?

"........by a man and a woman, who are " seems correct to me.

"Her ski's also are pink." is OK?
Her　ski's (=ski is) also pink.
or
Her ski's (boards) also are pink.
