I think packing a mixture of workout gear, lounge wear for by the pool and walking to/from the pool and tossing in a few dresses is key. After being there for so many days, you will probably want to dress up just a touch to make you feel good. Spending multiple days in workout gear can start to make you feel frumpy. So I’ve included a few cute dresses but I feel like you have a lot of this stuff at home. I really like the running and tennis shoes below.
Also, how adorable is the I know you don’t love sleeveless. You could always throw a t-shirt over one of her tennis dresses or just get one of the skirts. I think all of these go well with the white sneakers below. And, it’s really “IN” to wear like this ().
