We have been making these lovely bright neon yellow 4 way stretch velvet dance costumes with matching hair accessory included for a while now. If you measure your child correctly they are a great fit and are very stylish and eye catching on the dance floor, they are available in neon yellow, green, pink , orange and turquoise. These costumes are perfect for dance festivals and competitions. Here is a link to this costume in my e bay store
This style comes in ages 4-14 years and the hair accessory can be used to make a high ponytail or to go around a bun/top knot. This costume can be worn either way around, left or right arm in and if used for a duet you can both wear the same arm in or have the opposite arm in, they look great for solos or pairs, see pictures below.
The velvet is great quality, good stretch and very vibrant intense colour, even better this costume can be machine washed at 30 degrees and left to drip dry so it is easy to maintain.
