not sure if this is the right area but it is about clothing so fashion? lol

i wondered if anyone knew what the possible custom and import charges would be to get a formal dress sent over from america would be? I would estimate the dress would be maybe 3kg since it is the satin material ?

a friend's daugther has found a formal dress that she likes but cant get it in time here (they need 12-14 weeks!) but she could purchase one from america and receive in about 2-3 weeks.. just trying to work out whether cost wise it is an option.. and we are wanting to work out the hidden taxes for shipping it?

TIA!
