Quick answer
My child's dance costume doesn't fit
When the costume arrives and it zips halfway up, or hangs off the shoulders, and you have three weeks until recital.

Quick read
Call the studio director first: many studios have the next size up in their stock order, or they can arrange an exchange before the public recital order closes. If the costume came directly to you and exchange isn't possible, professional alteration is usually faster than an emergency reorder. The single most important step is to measure the child now and have those numbers ready when you call.
What to do
- Define the exact purchase constraint first.
- Shortlist two practical buying paths.
- Capture return, shipping, and fit risk before checkout.
Common mistakes
- Don't assume generic category advice beats studio or fitter requirements.
- Don't ignore return-policy constraints under urgency.
