Pre-Convention Preparation
Wear the full costume — including all undergarments and accessories — for a minimum of 2 hours at home before the convention. What feels fine for 30 minutes at home may be unbearable after 6 hours on a convention floor. Identify and fix any issues now.
Test your repair kit on a small piece of the costume material so you know what works before you need it at the event. Pack everything the night before and do a full checklist.
The #Boobcore Repair Kit
For structured costumes and corsets specifically: safety pins in multiple sizes (the universal fix), boning casing repair tape or strips of iron-on seam tape (for boning that pokes through), body tape for neckline and structural security, spare corset lacing (it breaks at the worst times), a compact steamer or wrinkle spray for fabric, and contact cement for any armour emergencies.
Heat Management in Structured Costumes
Corsets and boned costumes retain more heat than loose garments. Convention centres are warm. This combination requires active heat management: identify cooling areas in the convention space, schedule regular breaks from your costume (most convention centre bathrooms are air-conditioned), carry a portable fan, and stay hydrated. Know the warning signs of overheating and don't push through them.
Photography Strategy
Plan your photography ahead of time. Identify locations in the convention space with good light and clean backgrounds. Know your character's key poses so you can execute them quickly when photographers approach. See the convention photography guide for more detail.
Corset Care During a Convention
If you're wearing a bespoke corset: tighten to your comfortable wearing tension, not your tightest possible lacing. A corset worn at uncomfortable tightness for 8 hours creates a miserable experience. Air the corset out overnight — do not put it back into storage immediately after wearing.
Frequently Asked Questions
Yes, if the corset fits correctly and you're wearing it at a comfortable tension. An ill-fitting corset or one laced too tightly for extended wear is a different matter. Know the difference before the event.
Use your repair kit for immediate fixes. For more serious failures, most large conventions have repair stations or can point you to other cosplayers with tools. Don't panic — costume failures are common and usually fixable.
