The Non-Negotiable Repair Kit
Wardrobe failures happen at nearly every convention, and the difference between finishing the day in costume and not usually comes down to whether you packed a repair kit. At minimum: safety pins in several sizes, fabric tape (fashion or gaffer tape), a needle pre-threaded with a neutral thread color, spare adhesive if your costume uses it for support, and a small pair of scissors. This kit takes up almost no space and resolves the large majority of common on-the-day failures.
Packing Structured and Rigid Pieces Safely
Boned bodices, armor, and headpieces should travel in their own rigid case or box, never folded loosely into a soft suitcase with other items stacked on top. Curved or hollow pieces (breastplates, helmets) hold their shape better in transit if lightly stuffed with tissue paper or soft fabric — an empty hollow piece is far more likely to warp or crack under pressure than one that's internally supported.
If you're flying, seriously consider carrying structural pieces as carry-on rather than checked luggage; checked bag handling is rough on anything with boning, foam, or thermoplastic construction.
Support Garments Deserve Their Own Packing Priority
Bring the exact support garment fitted to each specific costume, not a generic spare bra — a costume built around one particular support piece's straps and coverage often doesn't work the same way with a substitute. If you use adhesive support, pack spare adhesive (it degrades with heat and humidity, and convention centers are often warm), and bring a lightweight backup support layer in case the structured option becomes uncomfortable partway through a long day.
A Simple Day-by-Day Packing Checklist
Lay out each costume by convention day rather than packing everything together — this makes it far faster to get dressed each morning and immediately reveals if you're missing a piece while you're still at home, not in a hotel room the morning of. Pack a labelled bag per costume containing the garment, its specific support pieces, shoes, and any small accessories, with the repair kit and skincare/adhesive-removal supplies packed separately since those get used across every costume, not just one.
