Alice is a very beautiful person, petite (the shortest of the Cullens at 4'10", "thin in the extreme", with small, "pixie-like" features. She is also described to have large eyes and long, delicate eyebrows. Her hair is cropped short, spiky, and inky black. She moves gracefully, continually cited as dancing, with a carriage that would "break any ballerina's heart", as described by Bella in Twilight. Also in Twilight, James states that, when they were human, Alice's blood smelled much better than Bella's. This could indicate that Alice was James's singer
Alice is portrayed as being optimistic, and she loves and cares for Bella like a sister. She often ignores other people's advice and does things her own way, which usually results in the outcome being better than predicted. She loves to sing with music three octaves higher than the song really is with her silvery bell-like voice. She has vicarious fun dressing up Bella "like a three-dimensional paper doll" and decorating for and throwing parties. She also loves shopping at expensive shops in large malls as well as makeovers. Alice seems to think that Bella should do everything a normal teenager should do (i.e. love to shop, party whenever possible, etc.). Alice is also described as being a very fashionable person, going on massive shopping sprees with the money she helps her family make by predicting the stock markets. Alice enjoys buying clothes for Bella. In Twilight, Bella complains to Edward that Alice was treating her like 'guinea pig barbie'. In Breaking Dawn, Esme furnishes a cottage for Edward and Bella, and Alice stocks the closet with an overflowing amount of clothing. Alice is often disappointed when Bella doesn't dress as she wishes. When Bella turns up wearing jeans and a t-shirt Alice says "Look at you, you need me to show you how to use your closet!" Her adoptive sister, Rosalie Hale, shares her intense love for fashion. Although Alice and Edward are very close, Edward often playfully calls her annoying, as he says in Eclipse when she is telling Bella about the graduation party. Edward and Alice have learned how to have a sort of mental conversation, and the family rarely notices. However, when they do notice, they will often complain about not knowing what the information is.
