A fashion challenge, you scoff? Let me correct you, dear reader. I will be in a foreign country with a different climate and different cultural views on what is appropriate. It's tropical and their rainy season with an average temperature in the 70s. Though the internet also tells me that July and August are a "dry spell" in the rainy season. I'm mostly going to school, but I've signed up for field trips, and I believe two of them are overnight (Camping? yeesh...). I'm taking a photography elective and who knows where we'll be trekking for that. There might be some fancy event that implies the need for fancy-ish clothes. Like if there's a school banquet or my Catholic host family insists I attend mass (which I might not mind because I could overlook the meaning of the words while just trying to figure out what is being said). Plus I want to go exploring San Jose and hiking. All these different types of event require different types of wardrobes!
Interesting language/culture tidbit:
In the United States, generally June, July and August are considered the summer months (el verano). But in Costa Rica, el verano occurs when the weather is most dry, usually December-April, which in the US is usually el invierno (winter). May-November is the rainy season in Costa Rica or el invierno. Note that Costa Rica is north of the Equator.
