So, let's start!
Birthday party themes for adults:
The classic theme that never loses relevance is first on our list - 40 & Fabulous.
Following closely behind is the party idea for men - James Bond - the perfect one for men who appreciate sophistication and style.
Third is the incredibly rapidly gaining popularity theme - A Tini Bit Older. This theme is divided into two colour schemes: some prefer olive green, others cream-coffee, and both options are magnificent.
The fourth position is occupied by Coquette Style Theme. Very stylish and cute decor in cream tones with black bows - the result is always simply charming. This style is fashionable to implement with helium balloon sets, adding bows as accents. Visit our online balloon shop in Guildford to find balloons in this style for 30th, 40th, and 18th birthdays.
The 5th point is the always popular and brilliant Hollywood with its red carpets, spotlights, and cutouts of Hollywood stars.
All these adult themes pair beautifully with light-up numbers, shimmer walls, balloon garlands, and helium balloon centrepieces. Thanks to our large assortment of colours, these decorations can complement any theme!
As for Children's Birthday Party Themes, while princesses and superheroes maintain popularity, here are all the trending themes for 2025 according to Guildford and Surrey parents.
