We learn a lot about Della from the fact that she has to sell her hair in order to buy a present for Jim. We learn that Della is a generous person. She really wants to get Jim a good present that expresses her love for him, and she does not want money to be a limitation for this. Moreover, we learn that Della is not selfish, because as much as she loves her hair, she puts Jim's happiness ahead of it. Finally, we learn that Della is deeply in love with Jim, to the point that she is willing to sacrifice one of the most valuable and dear things that she has.
Della's financial situation constrains her, but her selflessness helps her overcome that constraint. She loves and understands Jim well because she knows that the best Christmas gift for him would be the chain for his prized pocket watch:
It was even worthy of The Watch. As soon as she saw it she knew that it must be Jim's. It was like him. Quietness and value—the description applied to both. Twenty-one dollars they took from her for it, and she hurried home with the 87 cents. With that chain on his watch Jim might be properly anxious about the time in any company.
The strength of Della's love and her willingness to sacrifice for him is clearly demonstrated when she cuts off her hair to buy the chain. Her hair is something she values, and sacrificing it possibly made her undergo an internal conflict:
So now Della's beautiful hair fell about her rippling and shining like a cascade of brown waters. It reached below her knee and made itself almost a garment for her. And then she did it up again nervously and quickly. Once she faltered for a minute and stood still while a tear or two splashed on the worn red carpet.
