Not looking like the adult

[Ladybug223]

As the subject says, I don’t look like the adult. For context I’m 32 and have a step daughter who is 16. Whenever we are in photos together everyone comments how she looks older than me. I have a DS with her father and she seems to enjoy people thinking he is hers.
A bit of a silly post and I’m not sure what I’m asking for but how can I make myself look more like the adult

Grow up

Does she wear lots of heavy make-up and false lashes? Sometimes those wee lassies make themselves look 35 with all the contouring and what not...it can be a hard look.
It may be more a comment about her than you iyswim?

There aren’t many 16 year olds who genuinely look in their thirties.

What do you wear?

It doesn't follow from your post that they think you look very young, let alone like a teenager. It seems more they think she looks older for her age, perhaps because she wears heavy makeup and tight or revealing clothes.
