Summarize:

A large bag is essential for any pool party, as it will hold everything that you might need. Fortunately, your bag doesn't have to match a theme or even your outfit. Aim for any cute patterns or colors that you like. Just make sure the bag is big enough to hold everything you need don't make it too big though. Try getting a beach bag that has hidden pockets, that way you can hide any personal items, such as sanitary napkins, or valuables, such as your phone. The material isn't important, although you should consider that your bag may get wet. If you have a leather or suede bag, this might damage the material. Choose what makes you feel great. Just because this is a pool party doesn't mean that you shouldn't wear jewelry. Part of being fashionable is wearing the perfect jewelry for the occasion. You want to accessorize, not decorate, so practice moderation. Consider simple earrings and a thin, chain necklace. Or, go bold and wear a chunky necklace or even a long, beaded necklace with accompanying earrings. You can also stack bracelets for a cute look. Don't wear your best pieces to a pool party, as you run the risk of losing them or getting them wet. If you're going to swim, consider putting your jewelry in the secret pocket of your large bag while you're in the water. A simple and always-appropriate accessory for any pool party is a hot pair of sunglasses. You need to protect your eyes from UV rays, and sunglasses scream fashionable. Try to wear some designer sunglasses if you have the money. If not, there are some cheaper imitations of the real deal at most box stores. Get a pair that you feel compliment your face shape. A sun hat is another great way to protect your eyes and will also keep the sun off of your face. Sandals or flip flops are the most fashionable and practical choices for any pool party. You don't want to wear expensive footwear to a pool party, as they will surely get wet. Instead, choose less expensive, comfortable shoes that complement your outfit. Big, box stores and even discount shoe retailers are a great source of cute summer shoes. Your beach towel should be fun or brightly colored, and most importantly, it should be big. Your colorful towel will not only attract attention, but it will be big enough for others to sit on while they talk with you.
