Teams decide what they want to wear. Some players like to create matching outfits during competition. Doubles is about you and your partner so whatever you decide is fine. At grass events, most girls end up playing in t-shirts or sports bras and spandex. At the beach, many wear bathing suits. This is practical -- the sand gets in your clothes so a two-piece suit is more comfortable. NOTE: Bathing's suits are fine at the beach but you rarely/never see that at a grass tournament. Play in a tank, sports bra or t-shirt and shorts or spandex....
Grass doubles players should wear sturdy tennis shoes that won't slip. Avoid running shoes with nubs on the bottom. You want stability on a grass surface, but you don't want your shoe to be too smooth either. Some experienced grass players like to play barefoot. This almost always ends badly. Don't do it. The grass doesn't give like the sand does. Wear sturdy shoes.
Sunglasses are an essential part of outdoor play. Do not forget to equip your players with good sunglasses. (even if the forecast is cloudy, bring sunglasses) This is so important and every year someone forgets. Be a good teammate and bring a backup pair of sun glasses just in case one of your teammates forget! .
Sunscreen is a MUST. Also consider a baseball cap or visor. You are outdoors all day for the first time in a year. Protect your skin and eyes. Please be smart about the sun.
Parents -- please talk to your teammates to coordinate outdoor tents. Sharing tents is a great idea. Everyone will need a shelter because there is a fair amount of downtime in doubles. The girls will be tired after playing and will need shade, food and water to recover. Bring extra outdoor chairs, blankets and towels and everything you need to be comfortable outdoors. Think like a camper and come prepared! Plan to meet early so you can set up your tents next to your teammates to enhance the party atmosphere..
Bring coolers filled with ice and water and food plus lots more food and more ice and water!!! The most important rule of doubles: Your success is directly proportional to the amount and quality of the food you bring!! (Yes, this is an official rule) Bring extra chairs and blankets to welcome visitors to your tent.
