Collar problems :/

So I've almost managed to save up enough money to buy an AP blouse (first brand yay xD;;) and I really like this one:

But I'm concerned about the sort of double-collaring thing going on there. I'm going to be wearing this blouse under jumpers and over skirts, and I'm wondering if the second layer, which reaches to the sleeves, will look stupid under a jumper, or if it'll be fine.

Can anyone help me out here? xD Advice, opinions, or especially pictures of that style of collar under a jumper? All is helpful~
