Looking for a bts themed party with plenty of purple and a little something extra? Think photo backdrops, BT21 cupcakes and a bright yellow Butter cake.
These ideas give you lots to choose from, whether you’re decorating a whole room or putting together a small birthday table.
You can keep it simple or go all out. Start with your favorite photos or song, then pick a few decorations and treats to match.
I especially love the tiny balloon flowers!
BTS party ideas worth saving
purple fringe and photo prints
We’re starting off strong with this shiny purple photo wall. The silver BTS balloons and oversized number seven look so cute above the scattered group pictures.
Try hanging your favorite prints at different heights across a fringe curtain. Add a purple heart balloon if you want that extra little detail.
burgundy photo cake
How gorgeous is this cake? I love the deep burgundy piping around the group photo.
The little white border and matching bows make it even prettier.
Bring this picture to your baker if you want a photo-centered cake without the usual purple decorations.
balloon flowers and a giant logo
If you are looking for an all-out backdrop, then this one is for you. There’s so much to love, from the tiny balloon flowers to the huge purple balloons along the side.
The tall logo panel and black display stands keep the BTS theme clear. Try a few reflective silver balloons among the purple ones to follow this setup.

colorful BT21 cupcakes
OMG, how adorable are these BT21 cupcakes? The pink bunny ears and little blue koala face are my favorite parts.
Arrange some on a white cake stand and the rest on a board below, just like this. Each character gets its own little spot without needing lots of extra decorations.
a purple balloon gift
This is such a cute way to make a birthday balloon feel more personal. Smaller purple balloons sit inside the clear outer balloon, with long purple ribbons hanging from the bow.
For your own version, add the birthday person’s name beneath a BTS design. The patterned gift box at the bottom is a fun detail too.
bright yellow Butter cake
Don’t want to stick with purple? No problem! This yellow Butter cake gives you a completely different color to work with.
I am obsessed with the black outlines and white highlights. They make the heart-shaped cake and melting-puddle design look like a cartoon.
a corner photo collage
If you’re looking for a smaller decorating idea, try a photo collage like this one. A large group picture stretches across the corner, with portraits and smaller prints arranged around it.

You could use this as the starting point for a party lounge corner. Pick a few larger pictures first, then fill the spaces with smaller favorites.
logo pancakes and blueberries
Who says your celebration has to start with cake? This pancake stack has blueberries around the edges and two pale yellow pieces arranged into a BTS-style logo on top.
The little RJ plush beside the plate is adorable. Save this idea for a birthday breakfast or a smaller brunch celebration.
pastel Dynamite cake
I am obsessed with this Dynamite cake. The pastel waves are so pretty, plus that tipped ice cream cone is such a fun extra touch.
There are donut, cassette and ice cream truck decorations tucked around the cake. Keep those playful details if you want to build your party around the song.
life-size photo standees
Want a photo spot without covering an entire wall? These two life-size standees give you a simple place to start.
Purple, white and silver balloon clusters sit behind them. You could add your own birthday lettering across the top rather than copying the letters shown here.
pink fringe and letter boxes
This is another pretty fringe backdrop, but it’s a little different from the first one. I love the stacked BTS letter boxes beside the table and the purple balloons across the top.
Hang a birthday banner over the pink fringe to bring the setup together. A standee on the opposite side gives you another spot for photos.
pink teal and purple balloons
The pink and teal balloons are so cute in this setup. If you want your decorations to look a little different, mix them with purple and black instead of using only lavender.
The black backdrop has a large pink BTS logo in the middle. I especially love the BT21 characters on the side pedestal.
black and white party favors
How cute are these matching pens and keychains? The white hearts, black bows and little BTS letters look lovely together.
Try the same black-and-white colors for your favor packaging. You don’t need to copy all the printed wording to get this coordinated look.
a cup noodle station
A noodle station is a fun option for the food table. This one has stacked noodle cups, a hot-water dispenser and toppings set out beside them.
I love the character cutouts beside the cups and the little group-picture sign. Keep the tiered arrangement for your own table, then add BTS or BT21 pictures if you’d like another personal touch.
lavender treats and flowers
This dessert table may just be one of my favorites. I love the lavender logo treats beside the pink and purple flowers.
The hexagonal cookies are so pretty too.
Use white stands at different heights if you want a similar arrangement. A deep purple runner brings another shade into the table without adding more decorations.
ramen packets and topping bowls
Here’s another way to set up your noodle table. This time, the packets sit beside little bowls of corn, chopped greens and other toppings, with cups and chopsticks at the back.
You could add purple food labels to connect this general ramen station to your BTS decorations. Keep any hot-water setup on a stable surface away from the table edge.
a pink and lavender invitation
Bring the theme into your invitations with a pink-and-lavender border and a big BTS logo. I love the photo cutouts around this black-centered design.
For your own invite, leave a clear space for the date, time and location. Replace the sample details before sending it to your guests.
purple drips and photo toppers
If you love a cake with lots of decorations, this one is for you. Purple drips, tiny music notes and star details cover the pale sides.
The large front portrait and group topper make this feel extra personal. Ask your baker to change the number and birthday message for your celebration.
purple balloons and glowing numbers
I know the balloon flowers above are adorable, but this purple balloon arch is another favorite. Mostly because the different shades look so pretty around the round group-photo backdrop.
The glowing number 30 sits beside a logo-covered cake pedestal. Choose your own birthday number and keep the BT21 and finger-heart stands if you like that mix of designs.
a photo sleeve for pink drinks
Last but definitely not least, we have this cute purple cup sleeve. I love the little hearts on the sides and the group photo across the front!
This one marks BTS’s tenth anniversary. For a birthday version, you could use a personalized message around a pink drink with dark pearls at the bottom.
