In January, I worked on the Detective Party Plan, which made me think about all the variations you could have of a detective party. And that, in turn, made me want to share with you something that we talk about in depth inside the Party Course: why it’s so important to niche down your party theme and style.

The Power of a Specific Theme
Why does theme matter? Let’s take a detective party as an example. While “detective” is a great starting point, it could mean:
- A Sherlock Holmes theme
- A private detective theme
- A police detective theme
- A spy or secret agent theme
While these variations might share similar activities like solving mysteries or cracking codes, their visual elements can be completely different. A Sherlock Holmes party calls for iconic elements like the deerstalker cap, Inverness cape, and magnifying glass, while a police detective party might feature badges and navy-and-black color schemes. The party decor, tabletop and even party favors would change depending on which type of detective theme you choose.

Without picking a specific thematic direction, your party risks becoming a collection of mismatched detective elements. That will make your party look messy and you’ll feel like something is off. Being specific about your theme makes shopping and crafting so much more straightforward since you have a clear vision guiding your choices.
That’s why for the newest party plan theme, I specifically chose a private detective focus. This decision shaped everything from decor to activities and even desserts.
The Impact of Party Style
Your party style is just as crucial as your theme. Party style is purely a matter of personal preference — there’s no right or wrong answer. Think of style as your party’s personality. It could be:
- Modern
- Retro
- Vintage
- Shabby chic
- Boho
- Art Deco
- Pop art
Let me share two different approaches to detective parties:
1. Modern Private Detective: My newest party plan theme features clean lines and simple shapes. We included contemporary props like evidence collection bags, LED flashlights, and a mug shot backdrop.

2. Vintage Nancy Drew: For my girls’ detective party, I went for throwback atmosphere that recalled the book illustrations:
- Silver candelabras
- A vintage typewriter
- An antique hand mirror for solving backwards codes
- A birthday banner crafted from classic Nancy Drew book pages
- An old-fashioned rotary phone for “calling the police”



How to Find Your Party Style
Not sure what party style you’re going for? Imagine a funnel:
- Start with your broad theme at the top
- Narrow it down through research and brainstorming — when you start imagining your party, what types of elements are you drawn to?
- Define your specific style
(Here’s a slide from the Party Course that explains the funnel metaphor.)

Here’s a simple way to check if you’ve found your style. Review your party Pinterest board and ask:
- Does my board show a consistent color palette?
- Do the pins share a similar feel?
- Would these elements look like they belong at the same celebration?
Remove any pins that don’t align with your vision and keep those that truly reflect your theme and style.
(And here’s one more slide that introduces the three Pinterest questions technique.)

Name Your Party
Here’s one more trick. Give your party a specific name that combines both theme and style. Instead of just “detective party,” call it “Glen’s Modern Private Detective Party” or “Rick’s Retro Police Detective Party.” This simple shorthand helps keep your vision clear while shopping and planning.
