Seemingly Mixed-Up Twins

I seem to be coming across a lot of these lately. You know, when same-gender fraternal twins look like they should have each others’ names.
I know 7 year olds, [name]Natalie[/name] and [name]Hannah[/name]. [name]Both[/name] are blonde, but [name]Natalie[/name] is very Bohemian looking with long wavy hair and [name]Hannah[/name] has a delicate face with pin straight hair.

Then there’s [name]Josh[/name] who is petite with blonde hair and big blue eyes, while his brother, [name]Riley[/name] has dark brown hair and eyes.

Oh and I live with 19 month old twins who people have made comments about them being switched. [name]Samantha[/name] has blonde straight hair and light eyes, while [name]Sarah[/name] has curly dark hair and eyes.

Obviously, i know this is an opinion, but it makes me wonder…if parents don’t name the kids alphabetically, how/why do they choose.

Anyone know twins like this?
