Help me style teenager for christmas meal

[Gingercatsrule]

Hi all ,
My daughter is 18 but Has some sen so emotionally about 13-14 she has been volunteering in a charity shop for a few months and loving it , she has been invited to the Christmas meal to the local restaurant and hasn’t got any idea what to wear , she is there tomorrow but then the meal is next week so could do with some help please wise mumsnetters xx

oh shes a size 16 and is 5 foot 5 ish

Any sensory issues?
any sense of personal style?

my teen with sensory issues is fond of the “academia aesthetic” so I use that as a guide for helping her shop.

Something sequin / sparkle on the top, with dark trousers, black jeans for example. Loads of options for sequins everywhere (at all price points) and that's probably what I'd opt for.

Christmas jumper is usually an acceptable option these days, I'm expecting a charity shop Xmas do won't be too fancy

Where do you/she normally buy her clothes?

Christmas jumper not a bad idea actually. Something like this with her best jeans?
