They are basically these in white, I don't know if they have a special name, everywhere they are called high waist trouser jeans:

Here's a fairly similar style:

I got mine form NM but they are not available anymore:

Btw, if you like the white pair I posted here ( they are bit lower and not so wide as the white pair I got), I have ordered them in dark denim and waiting for them to arrive, so I will post a photo and you can see the fit.
Edit: I forgot to say that SFAMK Ginger in white have similar styling ( but they are not trouser, regular 5-pocket) and are very nice, I tried them on at Nordie's past summer:
