T-shirt Size help

[Tashayarna]

Hello I wanted to buy one of the t-shirts but the sizes confuse me ^_^; its for a friend who is a UK size 12-14?

which one off the drop down menus do I pick? as it says Girls L 12-14 and then just Large 12-14? is one girls and one womens sizes? or is it american sizes and UK sizes? thanks!

I'm pretty sure it's just Women's and Girls' sizes. You'd have to use some sort of sizing chart to figure out the UK size.
