The Basics: Three essentials for traveling are sunglasses, a swimsuit, and a purse that can everything you need with you on the plane/road. I created a set that would suit four stereotypes of girls: boho, girly, edgy, and trendy (from left side to right). Personally I find I like to make a statement with these items because when on vacation outfits tend to be more minimal. I recommend bringing a couple of two piece swimsuits to mix and match, it looks funky and unique. Don't forget the sunscreen and towel!

Cover-Ups: Swimsuit coverups are vital for travel. You don't want to wear anything fussy over your swimsuit so the less pieces, the better. I love classic jersey dresses and rompers for those days that you just want to wake up and go.
Daytime Wear: Packing simple but cute tops and a couple of shorts are always your best bet for vacationing. They are easy to throw on and very non-fussy. When considering shoes to bring it's best to go with the pair that matches with the majority of your outfits. Personally I bring one bright sandal, one black sandal, and one metallic sandal.
Night Wear: Before I travel anywhere I like to research the attractions the city I'm going to has. It's always best to bring a couple pairs of jeans and at least one pair of heels in case you go to a fancy restaurant, club, or party. The fewer heels, the better since they take up a lot of space.

Outerwear: Keep things to a minimum and bring a cardigan in a neutral color and a bright hoodie for after swimming. The cardigan will dress up your outfit, while the hoodie will make you look a like a bright cutie near the water.
*Accessories: If you love accessories as much as I do I would advise to keep it to a minimum. I know I have definitely lost some of my favorite necklaces taking them on vacation with me. If you must bring accessories, I would recommend bringing studs or bracelets that you would wear the entire stay and a couple of cute headbands, it's very non-fuss but a little bit of sparkle can instantly upgrade an outfit.
