Here also we go in even numbers, except for juniors.
If juniors don't exist, then I'm 6-8 UK in bottoms (since size 7 US is a bit loose) and 10 UK in tops
The equivalency is such.
UK = 4 , 6, 12, 14, 16, 18
EU = 36, 38, 40, 42, 44, 46
US = 6 , 8, 10, 12, 14, 16
Just check it out Rachael
Maybe you were thinking Australian Sizes, there is 4 in difference between US and Aussie sizes (2 with UK).
