I dressed my daughter in princessy pink outfits as well as straight up boy's clothes. Whatever I happened to find in the store and think was cute.
I got rid of the really girly stuff but I did keep several articles of the girl's clothing for my younger son too.
Hilariously enough, gender critical parents always have "gender neutral" pics of their babies.
(It's weird, my family isn't really feminist - me being the exception - but they really, really hate gendered children's clothing. My mother judges people who dress their little girls in pink, very harshly. It's on par with owning an SUV. It's not really hard to live what they preach, too, because it's something of a family tradition to dress babies in hand-me-downs. Why waste money on something they'll grow out of anyway? So even if gendered items happen to turn up in the pool, they will inevitably used for all family babies. Not having suitable baby photos in case baby turns out genderspecial is such a luxury problem ... that only exists for people who can afford to buy all their baby stuff new.)
