The Sims 4

The Sims 4 Marketplace continues to expand in September 2026, giving players even more creator-made options for customizing both Sims and their homes. On September 3, 2026, three new Maker Packs arrived on the Marketplace: Replay Hair Set by MADLEN, Josephine Set by Mechtasims, and Dear Diary! Bedroom by ValiaSims. Together, the new releases add six Create-a-Sim hairstyles and 24 Build Mode items, with themes ranging from nostalgic hair trends to a Y2K-inspired teen bedroom and a comfortable home study space. For players looking for another way to jump into the game and explore its customization possibilities, they can also Buy The Sims 4 Account through a suitable marketplace. EA’s official Marketplace currently groups all three releases under its "Flashback to School" section, making them particularly fitting additions for the beginning of September.

The Sims 4 September 3 Maker Packs Overview

Unlike traditional Expansion Packs, Game Packs, or Stuff Packs, Maker Packs feature content produced by approved community creators for The Sims 4 Marketplace. This allows established creators to bring their designs into EA's official Marketplace ecosystem.

The September 3 lineup is divided between Create-a-Sim and Build Mode content:

That gives players 30 new customization pieces across the three packs, although they serve very different purposes. Replay Hair Set focuses entirely on Sim appearance, while Josephine Set and Dear Diary! Bedroom provide furniture and decorative options for building personalized interior spaces. 

Replay Hair Set Brings Six Nostalgic Hairstyles to CAS

MADLEN's Replay Hair Set is the Create-a-Sim-focused release in the September 3 collection.According to EA, the pack contains six hairstyles inspired by an era when hair was effectively an accessory in its own right. Rather than offering six closely related variations, the collection explores several different silhouettes and styling approaches.

Players can expect looks built around:

1. Statement ponytails and playful updos 

2. Softer bangs and layered styles 

3. Everyday cuts for less dramatic outfits 

4. Soft waves, polished looks, and bobs 

5. Hairstyles designed to work with both nostalgic and contemporary fashion 

EA specifically suggests pairing the hairstyles with denim, bright colors, and glossy makeup for a stronger throwback aesthetic, although the designs can also be incorporated into more modern outfits. The official product page describes the collection through three ideas: "What's Your Hair Mood?", "The Look Starts With the Hair," and "A Little Nostalgia Looks Good On You!" The emphasis is therefore not simply on adding more hairstyles to CAS, but on making hair an important part of a Sim's overall visual identity.Replay Hair Set was officially released on September 3, 2026, and requires The Sims 4 base game and applicable game updates. 

Josephine Set Creates a Stylish Home Workspace

The second September 3 release is Josephine Set, created by Mechtasims.Instead of CAS content, Josephine Set adds 10 Build Mode items designed around a comfortable and stylish workspace. EA describes the collection as a way to create a "dreamy office," combining organization with a softer visual style. The theme is broad enough to work in more than a dedicated office. EA specifically notes that the set can add personality to either a bedroom or office, making it useful for smaller homes where a Sim's desk and study area share space with their bedroom.

The collection is particularly suited to situations such as:

1. Studying for an important test 

2. Creating a student workspace 

3. Working from home 

4. Building a bedroom-office combination 

5. Designing a comfortable everyday desk area 

EA highlights "Cute and Functional" as one of the pack's main features. Another is "Colors For All Styles," with different color combinations allowing the furniture to fit into a wider range of interior designs. This makes Josephine Set a particularly logical part of the Marketplace's current Flashback to School selection. While Replay Hair Set addresses personal style, Josephine focuses more directly on the study and work side of the back-to-school theme.Josephine Set launched on September 3, 2026 and contains 10 Build Mode objects. 

Dear Diary! Bedroom Turns Teen Rooms Into Y2K Spaces

The largest of the three September 3 releases in terms of item count is Dear Diary! Bedroom by ValiaSims.The pack contains 14 Build Mode items and is specifically designed around a personalized teen bedroom with strong Y2K nostalgia.EA describes the concept as giving a teen Sim somewhere for "big dreams, messy drawers, loud music, and questionable fashion choices." Its visual ingredients include cozy furniture, fluffy textures, playful clutter, and dreamy lighting. Rather than presenting the bedroom as a pristine display room, the collection aims to make it feel like an individual teenager actually lives there. EA frames the space around moments ranging from relaxed afternoons to getting ready for a major night out.

Three Main Themes Define Dear Diary! Bedroom

EA divides the pack's identity into three feature areas.

1. Teenage Dream focuses on giving teen Sims a bedroom full of personality, combining furniture with cute clutter and lighting.

2. Blast From the Past! pushes the collection further toward Y2K nostalgia. EA even references the pre-streaming experience of rewinding a cassette to hear a favorite song again, reinforcing the retro inspiration behind the room.

3. Make It Yours emphasizes customization. Different swatches can change the room from soft and dreamy to colorful and playful, or create something more understated. 

This flexibility should make the pack useful beyond a single preset Y2K room. Players can mix individual pieces into different builds while retaining the collection's youthful style.

Why Are the Three Packs Grouped Together?

One of the clearest connections between these otherwise different releases can be found directly on EA's Marketplace.EA currently places Replay Hair Set, Dear Diary! Bedroom, and Josephine Set together under:

Flashback to School

The grouping makes sense when looking at their themes. 

However, players should not confuse Flashback to School with a traditional limited-time gameplay event. EA's current Marketplace presents it as a themed storefront collection. There is no official information in these sources establishing a limited gameplay event with a specific end date. 

The September Releases Follow a Busy August for Maker Packs

The three new packs also continue a broader expansion of Marketplace creator content.On August 31, 2026, EA published "Meet the Maker Packs Debuting in The Sims 4," highlighting a range of creator-made content that had arrived during August and saying that more was on the way. Some of the Maker Packs highlighted by EA included Soft Minimalism Living Collection by simspancake, Musical Note Collection by Newsea, Sweet Summer by Miiko, Sophie Set by SolunaRae, Country Morning by Kerriganhouse, Salon Glow Hair Set by MADLEN, Y2K Gamer by HYDRA, and The Little Plant & Garden Shop by SixamCC. That content spans a surprisingly wide variety of design categories, from hairstyles and fashion to cottage interiors, gaming rooms, plants, and decorative food.EA's current News & Updates page still lists the August 31 Maker Packs feature among its latest Sims 4 news, immediately following the game's August 25 free-content and performance update. The pace continued into September. Sims Community reported another Maker Pack, Soft Balance by Comiko, on September 1 before confirming the arrival of the three September 3 packs two days later. The site noted that six new Maker Packs had arrived in just over a week before the latest three were added. 

How Much Do the September 3 Maker Packs Cost?

EA's individual product pages confirm the contents and release dates, while Sims Community recorded the Marketplace pricing when the three packs arrived on September 3.

The reported prices were:

1. Replay Hair Set: 300 Moola, equivalent to $3 USD in the reported Marketplace pricing 

2. Josephine Set: 200 Moola, equivalent to $2 USD 

3. Dear Diary! Bedroom: 300 Moola, equivalent to $3 USD 

That puts the three packs at 800 Moola in total based on their listed individual prices. Players should remember that Maker Packs are individual creator collections rather than one combined September bundle. Each can therefore be considered separately depending on whether a player is more interested in CAS, interior design, teen bedrooms, or office furniture.

What the New Maker Packs Mean for The Sims 4 Marketplace?

The September 3 additions show how The Sims 4 Marketplace is increasingly being used to deliver smaller and more specialized collections alongside the game's traditional DLC structure.Replay Hair Set serves players primarily interested in CAS and fashion. Josephine Set provides a tightly focused workspace collection. Dear Diary! Bedroom offers the most Build Mode pieces of the three while leaning heavily into teen life and Y2K nostalgia.More importantly, the three packs illustrate how creator content can address specific aesthetics without requiring every player to buy a larger themed DLC. EA's Marketplace currently lists these packs alongside an increasingly broad catalog of Maker releases, covering everything from kitchens and living rooms to hairstyles, clothing, gardens, and children's bedrooms. 

For players interested in the newest Marketplace content, September 3, 2026 is therefore a notable date for The Sims 4. Replay Hair Set, Josephine Set, and Dear Diary! Bedroom collectively bring 30 new CAS and Build Mode pieces while covering three distinct customization needs. Players looking to expand their game beyond these creator-made additions can also explore Cheap The Sims 4 Game DLC for more ways to add new worlds, features, activities, and customization options. With all three Maker Packs currently featured in EA's Flashback to School selection, the latest releases offer a timely mix of nostalgic style, teen-room customization, and practical study-space design as The Sims 4 enters September 2026.
