We began by me going into the bedroom and opening up my closet door. 故事开始，我走进卧室，打开壁橱。
To open up means here to open the door. “To open up”在这里是“开门”的意思。
A closet, "closet," is a place, usually in your bedroom, where you put clothes—you store your clothing. 壁橱(closet)，是这样的地方，通常在你的卧室，那里你可以放置衣物。
You can also have a closet in other parts of your house, and it's usually a place where you keep things—you store things. 你房子的其它地方也可以设立壁橱，那通常是你放置东西的地方。
Well, I "open up my closet door" and I look at my dress shirts. 嗯，“我打开壁橱”，看着我的西装衬衣。
My dress, "dress" shirts (two words) are the nice shirts, the shirts that I can wear to work. 我的西装衬衣(dress)(两个字)是我能穿着去上班、质量很好的衬衫。
The opposite of a dress shirt would be a casual shirt, "casual." 与西装衬衣相对的是休闲衬衫(casual)。
A dress shirt is a nice shirt; something that usually has a collar on it. 西装衬衣的质量很不错;它一般会有衣领。
A collar, "collar," is the top of the shirt, what goes around the neck. 衣领(collar)在衬衫的上部，环绕着脖子。
Well, I look at my dress shirts and I look, also, at my pants, "pants." 嗯，我看看西装衬衣，再看看裤子(pants)。
