There was a comment from someone at DAZ quite some time ago, that much of the clothing for children of the ages represented with the MilGirls and MilBoys packages is sexually indistinct, ergo MilGirls clothing packages work fine with the boy. If only that were still true... Heck, I see 9 year old girls running around in things my fiance wouldn't be brave enough to wear in public. (it's sickening) And most of the boys are into one or the other of those clothing habits I can't wrap my head around, like pants so loose they hang a foot below their waist. All that said.. anything made for the Millennium Girls will fit the boys, it just may not be very "boyish."
