help me, I have no clue.

How old is she?

let's say in her 50s

Well you have lots of options depending on your budget and what she likes. Ideas are: bottle of wine, nice cardigan or coat if you know her size, blanket, chocolates, jewellery you can't really go wrong with that, flowers, maybe a bag or purse.

Usually when it's someone else's birthday you don't get anything.

lol, what do i get FOR her, u happy now? and thanks, @parisqeen

No worries, good luck
