Although you may think the idea of a gift certificate is boring, it may actually be a very practical gift if bought from the right place. There are some essentials for ballroom dancers in terms of attire. Ballroom dancing shoes are a necessity, as are practice clothes and performance or competition attire if she is at that level. You can buy these items directly, although sizes are sometimes difficult for shoes or clothes. A gift certificate at a local or online dance supply store would always be appreciated.
Another thing a ballroom dancer will always use is music. If you know which style of music or dance she specializes in, you can buy that style of music. Also, there are ballroom compilation sets that will have a few songs for each dance style. If you want to spend a little more, splurge for a diskman or MP3 player that she can take with her to the studio for practice sessions.
A ballroom dancer, whether a beginner or a professional, will always continue to perfect her craft. Find out where her preferred studio is or who her favorite teacher is, and enroll them in the class or treat them to a private lesson. If you are not sure which dance style they prefer, you can get give them a credit at the studio and they can use it towards whichever class or teacher they prefer.
Dancers always carry around a bag with their dance clothes and shoes. You can purchase a bag that is especially made to be a dance bag, which will have a dance logo or picture on it, or any bag large enough for a change of clothes and a pair of shoes will work. Choose a bag that will go along with her personal style.
