Practical and legal considerations that every cosplayer should be aware of before attending conventions.
Every convention has its own prop weapon policy. Check before building — most require foam or plastic only, peace-bonding of prop weapons, and no realistic-looking firearms.
High-value handmade costumes can be insured under specialist contents insurance policies. This is worth considering for elaborate builds representing significant financial investment.
Cosplay of copyrighted characters sits in a grey area of IP law in most jurisdictions. For commercial use of costume imagery, take legal advice specific to your situation.

Common Questions
Most major conventions do enforce policies at bag check or a dedicated weapons check-in, and enforcement has generally gotten stricter over time. Always check the specific convention's prop policy in advance rather than assuming last year's rules still apply.
For costumes representing significant time or material investment, some cosplayers use scheduled personal property riders through renters or homeowners insurance, or specialty hobby-item policies, to cover damage, loss, or theft while traveling to conventions.
Cosplay for personal, non-commercial use (wearing a costume, attending conventions, posting photos) is broadly considered fair use in practice and rarely leads to legal action, but selling costumes or using a character's likeness commercially carries more IP risk and is worth understanding before monetizing.
