1.) Wear a chiffon blouse. There are some Jsks that can look nice without a blouse. But wearing a blouse, even when its hot, holds the benefit of protecting your dress from sweat (eww). Keeping dresses in good condition is important to many lolitas. Especially for those with "revolving closets" that tend to buy and sell their items alot. A chiffon blouse is light weight, and having extra coverage on your shoulders can help prevent a painful sunburn. Loliable chiffon blouses are also easy to find at many popular mainstream clothing shops.
2.) Carry a parasol. Parasols are fantastic. I bet every person writing on this week's topic will mention parasols. They are a feminine, frilly, and pretty accessory with a victorian flavor. They also come with the benefit of personalized shade.
3.) Short socks/ crew socks. For whatever reason, I always grew up calling these "bobby socks". Though I personally can't pull them off they can be use to create very cute coordinates.
4.) Go with natural hair. The wig may tempt you with its promise of beautifully, perfect, already styled hair. But it's appeal will quickly wear off when it becomes a nuisance that you can't take off while out and about.
5.) Be mindful and considerate if you are hosting a meetup. Pick indoor locations, like the movies, or a tea house. Some botantical gardens, zoos, parks ext will have events at dusk during the summer if you want to do something out doors.
6.) Go with lighter colors. This one from Angelic Pretty is a great example of a very cute summer time coordinate that incorporates many of the tips I've mentioned here.
7.) Keep hydrated! Here's a recipe for Disney Land's famous (non-alcoholic) mint julep. It is cool and refreshing, I always look forward to it when I go there :D
