Is it still okay to buy the pink school apron for girls?

There's no rule written anywhere about what color a school apron should be. It depends a bit on the school, what they ask for, and most importantly what your daughter wants. If she prefers pink, why not? Some schools are still traditional about these colors (pink for girls, light blue for boys), others don't really care and let kids choose, and some require a neutral color like white or gray. The best thing is to check the school's regulations or ask directly at the office what they require.

That said, honestly most parents today don't worry about it that way anymore. If the girl wants pink that's fine, if she wants blue that's fine too, if she wants red or green even better. An apron is practical clothing, it gets dirty, you wash it, and that's it. The color doesn't determine anything. If the school doesn't have specific requirements, just buy what she likes and be done with it - that way at least she'll wear it without making a fuss in the morning.

Most schools these days don't have strict rules about apron colors anymore, so it really depends on what your school asks for. If there's no specific requirement, pink is totally fine if your daughter likes it, but other neutral colors like white or light blue are common choices nowadays too. The important thing is that it's comfortable and durable, since aprons go through a lot during the school day.

The first step is always checking what the school regulations say, because some schools really do have strict requirements and if you buy the wrong color you risk having to change it. That said, if the school doesn't specify anything, pink works perfectly fine - the important thing is that it's a school apron in the right size and durable, because kids are rough on them and after a few weeks of washing everything fades. If you've still got any doubts, a quick email to the teacher doesn't cost anything and clears up the uncertainty.
