Wedding help!! Arms covered, below knee, no pattern... help!!

[WillyWonkaIsAWanker]

I can't find a thing to wear for a wedding next weekend! Must hide flabby arm tops, and fat knees. Mid calf is perfect. I can't do big patterns but happy in red, green or blue. Or grey and black but never sure about them for weddings. Need shoes too. Have to be flat!! Could I get away with patent ankle boots?? Or show me some flat shoe suggestions pls?! I'm starting to panic.

Size?

Budget?

Relative formality of wedding / venue / other guests?

Thank you!!
Size 12-14
Budget up to £60 for dress/jumpsuit. £40 for shoes.

Not massively black tie formal but smart. Have a work awards do at a posh hotel the following week so would like it to be able to double up.

Hmm maybe something like this?

They have it in red too

Lovely dress Autumn... don't think I can do off the shoulder though x

& Other Stories have loads of midi wrap style dresses in the sale.

Pretty kitty fashion has some lovely dresses in all different sizes I'm sure you would find something on there.

You could definitely get away with wearing this with black tights and ankle boots

Could dress it up with gold accessories. It's v flattering and looks more expensive than it is imo!
