Inspiration; Boys from the past

There's heaps of cute stuff you can sew for girls, not so much for boys, it seems. I'm plugging away at this problem, and lately I've started looking at some historical styles for ideas.
Today I found this great found photographs profile on flickr, which is chock-full of inspiration!

I've been playing with the idea of a sailor suit for a little while, and thinking about how the neckline on a top would work. So it was cool to find this collection of photographs from Denmark (I think?) featuring lots of little boys in sailor suit-esque clothes. Check out the pants in that second shot, too! LURVE the button embellishments on the outside of the shorts legs, though I'd like to lengthen the short if I was going to do something similar.

I also really like the front of the coat the little boy in the front right of this photo is wearing - the decorative double-breasted look and the short waist is really sweet, especially with the over the knee, tight pantaloon.

Of a slightly more recent age (but still cute) are these shorts with attached braces (thought again, I'd like to see them around knee length, instead of teeny tiny 60s-style).

And I can't decide if I actually like these two pictures, or if it's the kid's slightly guilty expression that's giving me a fit of the giggles, and making the clothes seem more appealing.

Surely if it were the cuteness though, I'd be wanting reproduce the outfit of the marshmallow baby pictured here? Zie's so squishy! Like a baby marshmallow!
