Tip 1: Pack ONLY the essentials 🤓 You don’t want to bring anything that you’re not 100% sure you’re going to use 🔥 I’ve made the mistake of packing a couple of cute little dresses that I’ve had in my closet for months thinking that I’d want to wear them. I never do. Clothes that you don’t wear at home are not going to be worn while traveling either. They’ll just end up taking up room in your bag. Remember, less is more. If you end up needing a dress you can always buy it when you get to your destination. 
Mexico City is quickly becoming a hit with all types of travelers: backpackers, art and culture lovers, foodies, and history buffs. As a metropolitan capital city, it’s also very fashion-forward, especially in some of the trendy neighborhoods where you’ll find yourself grabbing an amazing meal or enjoying cocktails on a rooftop.Because of the altitude, Mexico City does not get as hot or humid as other parts of Mexico, even during the summer months. Daily highs reach the low 70s in the winter months and 80s in the summer. The temperature also drops quite a bit at night, with lows of 45°F, so layering is key for when you’re looking to transition from daytime exploring to dinner and drinks at night. It can feel humid during summer, and this is when you experience more rainfall. 
Anearthlyparadise.com goes on to mention that you can expect similar temperatures to summer during the day, but it gets chilly at night. Highs are 73 F (23 C), and lows are around 41 F (5C). You also probably won’t see a drop of rain if you come during the winter, so if you don’t want to deal with sporadic thunderstorms, coming at this time might be perfect for you. December is a very popular and beautiful time to visit Mexico City. You won’t have to avoid rain showers and the sky is its bluest during the winter months. People are often surprised at how chilly it is so make sure you keep reading to find out what to wear in Mexico City in December. (last edited 60 days ago by Mindy Nickerson from Jamnagar, India) 
Based around an article from tripsavvy.com, inland, for example in Mexico City and in Mexico’s colonial cities, people generally dress more modestly than they do along the coast and in beach destinations. Although it’s changing a bit over time, women in Mexico’s interior destinations seldom wear shorts, and men almost never do. Women who don’t want to attract excessive attention from men would be well advised to avoid short skirts and shorts and revealing clothes in general, but especially when traveling alone. Lightweight pants and long skirts are good options, as are blouses and tops that cover your cleavage. Sleeveless tops are acceptable, tank tops less so.
