Winter (alternative/arty) wedding guest

[BunTooti]

If you were going to a pretty casual wedding that was full of arty types, musicians...cool people what would you wear?
I lean more towards a grunge look anyway and normally put doc martens and a leather jacket with everything. Lots of black.
Size 12 top 14 bottom hourglass, mid 30s, 5' 4", olive skin, dark hair and eyes, don't really want to spend more than £100. Would like a dress or top and skirt. Possibly wide leg jumpsuit.
End of December so long sleeves would be a bonus.

I like the shape of this, with maybe over the knee sock boots. Kind of 70s vibe.

Love the dress & i actually think it goes great with boots.

Love that dress- buy it!!!

It's the only contender so far. Nothing else has made me go ooooooh

Lovely dress.
Not sure about the over,-the-knee sock boots with it though. Totally changes the vibe of the dress and tips it into more night out territory.
8hole docs- better.

Docs fine with me.

Any suggestions of where to look for dresses online? Thanks.

What kind of budget? Designer, I always think the Outnet have unusual styles.

OP says less than £100

I wish somebody would invite me to a wedding, so I could have an excuse to buy this beauty. Over budget though.

I saw that Topshop dress earlier, definitely the sort of thing I'm thinking of, thank you.

Then it lead me down a path that resulted in me almost buying a dark green satin midi skirt but then I couldn't find a top I liked.
