Just spent all afternoon looking for something to wear out for birthday drinks. Went to two different towns. Didn't even try anything on. 
Why can't I find anything I like? Don't want to be the stereotypical mum who wears a sparkly top and jeans or trousers. But I rarely go out in the evening anymore so I don't really have anything and I don't know what to buy.
Can someone help me? I have black and dark skinnies so could wear those with something. I have boots and heels. I have a couple of Blazers. I'm going to a pub so if I find a dress it needs to be casual. All the stuff I've seen in the shops looks so shapeless, garish or just just drab grey, or high necked and won't suit me, or too young for me (39). Tops all look like cheap and polyester-ish now.
I used to be fashionable! I just don't know where to look anymore. I am quite short, size 10 but large of bust. Budget £80 so not much! 

please help me?
