It is an excellent choice for beginner cosplayers looking for a comfortable, recognizable, and modern costume for conventions.

Complete Costume Breakdown
Clothing & Core Pieces
The base of the outfit starts with a simple light blue muscle tank top for a relaxed, sun-drenched summer feel.
Pair the tank top with comfortable grey sweat shorts that allow easy movement and all-day wearability at any event.
For her alternative signature look, you can layer a classic white T-shirt under a dark green spaghetti strap dress.
This layering style gives you options to replicate different scenes where Peg is desperately managing Birdie’s public relations disasters.
Focus on finding fabrics that look lived-in and slightly wrinkled to match the character’s realistic and busy vibe.
Make sure the clothing fits loosely to capture the casual, breezy beachside aesthetic of the private Greek island resort.
Selecting breathable cotton blends will ensure you stay cool while representing this hard-working, iconic film character.
Accessories & Details
Shield your eyes from the bright Greek sun with a trendy, distressed denim bucket hat that adds instant style.
Keep your hands free to handle emergencies with a practical black canvas belt bag worn snugly across your body.
Complete the look with simple black strappy sandals that are both stylish and suitable for walking on sandy beaches.
Carry a reusable red solo cup as a fun, recognizable, and inexpensive prop to complete the Greek party scene vibe.
These specific details tie the whole ensemble together and instantly make the outfit recognizable to movie fans everywhere.
Keep the accessories functional and minimal, just like Peg would, to stay completely true to her character’s personality.
You can also carry a notebook or smartphone to reinforce her role as a dedicated and stressed personal assistant.
Cosplay Tips
1. Lightly distress the denim bucket hat with sandpaper to make it look like a well-loved travel accessory.
2. Adjust the black canvas belt bag high on your chest for a modern, fashion-forward, and practical streetwear look.
3. Keep your makeup minimal, natural, and slightly dewy to reflect Peg’s busy, no-nonsense lifestyle in the Greek heat.
4. Style your hair in messy, loose beach waves peeking out naturally from under the denim bucket hat.
5. Carry a fake smartphone displaying emails or social media alerts to act like you are managing Birdie’s accounts.
6. Practice a slightly worried or alert facial expression to perfectly capture Peg’s character in photos and interactions.
Character Vibe & Styling Notes
Peg’s vibe is a distinct mix of high-stress assistant energy and effortless, low-key Mediterranean resort fashion.
She is constantly on edge, so dynamic posing like checking a wristwatch or typing frantically on your phone works perfectly.
Walk with purpose and look slightly exasperated to instantly bring the character to life when interacting with others.
The contrast between her casual clothes and the wealthy environment of the island is key to her character design.
Choose neutral tones and pastel shades to keep the costume grounded, realistic, and authentic to the film’s aesthetic.
Focus on comfort so you can enjoy your convention or party without worrying about restrictive or heavy costume pieces.
Emphasize her protective nature by standing defensively if you are cosplaying alongside someone dressed up as Birdie Jay.
