Gym Leader Flannery DIY Costume Guide

Flannery’s design leans heavily into casual, warm-weather streetwear, contrasting simple garments with dramatic hair. The core outfit consists of a fitted black crop top marked with a flame symbol, low-slung flare jeans anchored by an oversized red belt, and understated black footwear.

Because the individual clothing items are straightforward everyday pieces, the success of the build hinges on getting the hair silhouette right and cleanly applying the flame emblem to the top. The rest of the outfit comes together through careful fitting and proportion.

The Flame Crop Top

Flannery wears a sleeveless, high-neck black crop top that sits above the navel. A basic stretch-cotton or spandex-blend crop top serves as an effective foundation here, provided it fits snugly without pulling across the chest.

The defining feature of the shirt is the stylized red flame centered across the chest. Off-the-rack tops rarely include this graphic, so using red fabric paint with a homemade stencil gives you the cleanest result. Cut the flame shape out of freezer paper or adhesive vinyl, press it securely against the fabric, and dab the paint on with a sponge brush in thin layers. Stretching the shirt slightly over cardboard while painting prevents the design from cracking once worn.

Jeans and Belt Styling

Her pants are classic medium-blue denim with a noticeable flare through the calves and hem. A mid-rise or low-rise cut matches her illustrated proportions best, leaving space at the waist for her belt.

Flannery’s belt is unusually broad, bright red, and sits loosely over the waistband rather than threaded through standard belt loops. A wide cinch or waist belt with a simple buckle works well. If the belt tends to slide upward as you move, tacking small safety pins or strips of hook-and-loop fastener between the inner belt lining and the jeans waistband keeps it resting at the proper hip angle throughout the day.

For footwear, Flannery wears plain black slip-on shoes that remain mostly hidden beneath the wide flare of the denim cuffs. Simple canvas or faux-leather flats match the minimal profile of her original artwork without competing with the rest of the outfit.

Tackling the Voluminous Ponytail

The hair is the most demanding component of the entire costume. Flannery sports intense crimson hair pulled into a high, exploding ponytail with multiple spiky sections shooting upward and outward, along with two long sections framing her face.

Starting with a long, dense red base wig is essential. Standard gravity-defying spikes cannot hold their shape under the weight of synthetic fiber alone; you will need to backcomb the ponytail base thoroughly and build an internal armature—such as lightweight craft wire or carved high-density foam wrapped in matching wefts—to support the dramatic upward sweep. Heavy-hold hairspray and a hairdryer on low heat set each cluster firmly in place.

Trim the front bangs into jagged points that taper along the jawline, keeping the spikes separated with a small amount of styling wax.

The Pokéball

Carrying a standard red-and-white Pokéball gives your hands something natural to do during photos and immediately ties the casual clothing back to her role as a Gym Leader. A lightweight replica ball fits comfortably in hand or can be tucked against the hip alongside the belt.
