Chelsea is the youngest of the sisters and knows how to work her cuteness well. This adorable 6-year-old always seems to come up with the exact super-cute thing to say in order to win over her sisters and their friends. Though, very cute, she is shown to be a bit demanding, competitive and very clever. She is also very sweet. Curious and full of questions is part of her personality.
Chelsea is fair-skinned and has blue eyes. She also has platinum blonde hair tied in pigtails tied with a bow on each side.
In Season 1, she ties her pigtails in sky blue ribbons and decorates herself with a shiny teal bead necklace with a small pink bow on it, and wears a pink dress with the first half (torso) has ruffles and frilled sleeves, with the second half (skirt) having a multicoloured stars & hearts pattern on it. She also puts on light aqua Mary jane flats with pink bows on them.
In Season 2, Chelsea ties her pigtails in bright pink ribbons and wears a fully pink shirt, of which has bows for buttons and puff sleeves. Her skirt is pink and consists of a waistband and a fuchsia pink bow pattern. Her shoes are similar to the ones in season one, with flat Mary Janes but a bright pink just like her hair ribbons and the bows located near the sides.
Chelsea is known to be cute and sweet. However, she is shown to be a bit demanding, competitive and very clever. Like most young children, she is curious and full of questions.
She has great relationships with Barbie and her sisters. She is shown to love Blissa most of all the pets. She is quite competitive when playing board games, as shown in Primp My Ride and also a fan of poker.
