Dinner date!
So a friend of mine intited me to his and his husbands house tomorrow for dinner. there's going to be another couple there which I know. But my friend told me that if I wanted to come he was going to invite another friend aswell. This friend of mine is always trying to find some one to hook me up with so I'm starting to think this is kind of a blind date. 

I don't even know if his friend is a guy or a girl and I dont know what to wear eighter. 
 
And I should bring something right? Like a bottle of whine?
 
okay well It's be fun, I think. 

But which outfit is the best? 
 
 
 
Btw, the you're my favoourit top is from Vinted, they gave me £9 to spend when I became a member and that's the top got :)
