Our local market store was awash with neon clothing a few weeks back, I know this as ds2 wanted some new neon socks, at a few pounds I happily obliged.
I have also noticed some kids wearing elastic ankled zippy jeans of late, I noticed because I had some.
Jelly shoes are also back on trend apparently, as both our student teachers wear them.
A big stack of skinny bangles up the arms for a girl...Claires? Or equivalent.
For a top simply knot a white t shirt at the waist, or if it's a boy cut the arms and neck off an old t shirt. That with jeans and neon socks is probably a compromise.
Have a great time, hope you haven't lost your diffuser accessory on your hair dryer don't skimp on the volumising mousse.
Watch "Bill and Ted's excellent adventure" with them to get them in the mood...a fab film!
