Going out outfit needed, help please?

[Datingdoris]

Hello,

Hoping all you stylish ladies can help me out. I'm meant to be going out on Friday for dinner and drinks with people from work, I never go on nights out so have no idea what sort of thing is acceptable to wear.

I am late 30s, size 10, tall, long dark hair, want to cover bad skin on chest and back. Going out with mainly younger people so want to look semi trendy.
Feel free to ask questions you think might help.
Can anyone help?

I'm a big fan of any sort of jumpsuit when you want to feel dressed up but still smart. ASOS have got loads that would cover up your chest and back, for example this one.. will have a look for others though.

Not letting me post the image!
