Hermione adapts to pureblood customs in a multi - faceted way. She uses her natural curiosity as a driving force. When faced with a new custom like the pureblood way of handling holidays, she delves deep. She might compare it to Muggle holidays she's familiar with to find similarities and differences. She also uses her empathetic side. She realizes that these customs are important to purebloods, just as her Muggle - born values are important to her. So, she tries to respect and follow the customs as much as she can while still maintaining her own identity. For example, when it comes to the pureblood dress code for formal events, she may not fully agree with all the elaborate and sometimes restrictive rules, but she'll abide by them out of respect for the culture she's learning about.
