Reading a Design's Silhouette, Not Its Proportions
The most useful skill in choosing a character is learning to separate the silhouette (the actual shape and structure of the costume) from the specific body proportions the character happens to be drawn with. Structured, fitted bodices, wrap styles, empire waistlines, and corseted designs all translate well onto a full bust because the construction already has room built in for shaping — you're adjusting an existing structure rather than fighting against one that assumes a flat chest.
Characters drawn with extremely tight, seamless bodysuits and no visible waist definition or structure are usually the hardest starting point, not because they're impossible, but because there's nowhere for a full bust adjustment to hide — every added seam has to be planned in from the very beginning of construction.
Costume Features Worth Prioritizing
Princess seams, structured bodices with boning channels, wrap or lace-up closures, and adjustable corsetry are the most forgiving starting points for a first full-bust build, because they were already designed to be shaped to an individual body rather than mass-produced to one flat template. If you're choosing between two characters you love equally, this is a genuinely useful tiebreaker — pick the one whose canon costume already has some of this built in.
Layered designs (a fitted underlayer with a looser robe, cloak, or overdress) are also worth favoring for a first build, since the fitted layer can carry the full bust adjustment while the looser layer disguises any remaining imperfect areas.
If You Choose a Flat-Chested Design Anyway
You can absolutely still cosplay a character whose canon costume assumes a narrow, flat chest — it just changes the project scope. Budget significantly more time for pattern alteration, plan to add structural seams the original design doesn't have, and go in expecting to make deliberate creative choices about how closely to preserve the exact source silhouette versus adapting it to actually fit and move well on your body. Many of the most celebrated full-bust cosplays of exactly this kind of character lean into that adaptation rather than fighting it.
