Posts under certain pages/categories

Hi guys,

Hopefully I’m not blathering around in circles when I try to explain this one!

What I’m trying to do is set posts up so they appear under a certain area on my site – if you take a look at Style Me Pretty vs Style Me Pretty Living, you’ll see what I mean.

SMP posts: “http://www.stylemepretty.com/” >> “http://www.stylemepretty.com/2015/09/25/smpwedding101-honeymoon-makeup-essentials/”
SMPL posts: “http://www.stylemepretty.com/living/” >> “http://www.stylemepretty.com/living/2015/09/25/mountain-pie-party-with-pressed-cotton/”

Basically, for my site I’d want all ‘main’ posts to go to “lady-rogue.com/postpostpostpost”
And the ‘others’ to go to “lady-rogue.com/bride/postpostpostpost”

Does this make sense? (If so, yay.) And is it theoretically possible? (Double yay.) And, finally if both those are yes, how difficult is it to do?

Thanks so much, guys – appreciate your advice.
