Wear what you want, enjoy the music, and that's it.
Most people who attend outdoor festivals in Japan dress in functional clothing, including outdoor brands. A waist pouch or a satchel would be perfect.
But this is Phuket. Such style is a minority.
Here are some snaps of the global heads who were dancing around with their "Aperol Spritz" in hand. Everyone was really enjoying fashion, music, and drinks freely!

The United States was represented by Andrew (IG.) from Boston:@andrew_stanjones18 (Japanese only). He travels the world and attends festivals in various places, and he "just loves the music and worldview of 'EDC.
I thought, "A festival is a place where you can enjoy fashion to the fullest, isn't it? Plus it's overseas, so I brought a lot of clothes to enjoy being more fashionable. I brought a lot of clothes to enjoy dressing up in my favorite clothes and listening to my favorite music. I wouldn't trade this time for anything! I was tipsy at 17:00 when he answered, "I'll be back soon.

The orange high socks caught the eye of Febrian (IG.), a travel blogger in Indonesia:@_febrian(Japanese only). He is a world traveler, and after Phuket, he plans to roam in Saudi Arabia. He also plans to visit Japan in the summer.
You know how this venue has the vibe of music everywhere you go? That's why I always want to drink alcohol, and 'Aperol Spritz' is a drink that I can drink at any time of the day. Compared to beer, it is by far the most refreshing, so everyone in Japan should try it!

Anisha (IG.) is a content creator, dancer, talent and many other faces:@anishathai) is a customer from Hong Kong.
It's my first time here and I've made a lot of new friends and danced like crazy! It's winter now, but when I drink the Aperol Spritz, I feel like it's summer. It's so easy to drink, so don't drink too much!

Chris (IG.), in full purple style, was dancing around from the light of day:@christopher.keane1) is from Texas. After all, this is what a classic festival style is all about!
You ask, "Do I always dress like this? I have a job, so I don't dress like this every day (laughs). (Laughs.) But this is an unusual place, so it's no wonder I want to be unusual myself, right? I wore my favorite color, purple, and gold sunglasses.

The grand finale of the show, THE CHAINSMOKERS, which will be the big show, and Jozi (IG:@jojagpangan(IG.) and Jai (IG.):@jaiagpangan) are super gorgeous twins from Manila. They have many followers and are the stars of Manila!
The whole experience was amazing! It's not often that I've been to a festival this big, but the music was great and the vibes were just so good. Check out our social networking sites to see how great "Aperol Splits" is. Don't forget to follow us ♡"

Tony (IG.) came a long way from Las Vegas, the home of "EDC."@onesuavestud.io(IG.) and Damian (IG.):@onesuavestud(The two are the first two to enter the competition from the other side of the world.) The two entered the race from right behind the Earth and were super cute in their matching outfits.
I'm wearing the same outfit as Tony. We prepared in advance and said, 'Let's wear these. I drink a lot of Aperol Spritz in the U.S., so when we got there and saw this booth, Tony and I were happy. So when we arrived at the venue and saw this booth, Tony and I were happy. I think I've probably had 10 drinks already (laughs)," says Damian.

Tsai and Su are Chinese influencers. The two, who are very popular on social media in their home country, recall, "It was a moment that could only be experienced here in Phuket.
I was most impressed by the atmosphere of acceptance of diverse values and people from many different countries. The climate was great. We almost drank "Aperol Spritz" for the first time, and I think it was my favorite drink to dance to (laughs). (Laughs) I regret that I didn't know about it before.

Ally (IG:@allie_means) and Keira (IG:@kiera.hurley), and Mia (IG:@miabuffington(Keira and Mia) are party lovers from the United States. Keira and Mia love Thailand so much that they volunteer there. Allie was dancing and twirling a cushion-like cloth!
I had so much fun that I danced from morning till night! Thailand is the best country. It's a place where you can unwind just by coming. We all love fashion, so when we go to festivals, we always put more effort into it. It's great to stand out, isn't it? We don't care what people look at us!
Although not shown here, the three of you danced the whole time and drank all night long. Thank you all for your cooperation!
