what if u are 14? can u still enter to a camila cabello concert with ur parent consent?

That would be up to the artist and their management

I took my 12yr old to a concert there two months ago they gave out wrist bands

Call the venue before hand to make sure. Usually they give out hand bands which the bartender checks to prevent underage drinking

Usually the shows will say under the information tab whether they are specifically 16+ 18+ or 21+ But I'd call the box office to specify
