What can I wear with this dress to keep me warm?

[TokyoSushi]

Outdoor event, outside for about 4 hours. Looks like it will be about 14 degrees and cloudy. What can I wear with this to keep me warm? I don't suit biker jackets!

Ooh that's lovely. No advice sorry.

I’d wear a long coat tbh.

It's long sleeved so I would wear anything. Maybe a wrap just in case

Long coat or chunk boxy cropped cardi?

Long belted coat.

A blanket

Blazer
Thick cardi
Thigh length coat

I'd wear a mannish style blazer.

How smart do you need to be?

You could just wear a coat over the top.

If not, wear a long sleeved thermal top and long slip, tights socms and boots?

A sleeveless chunky longline knit over the top? Or chunky cardigan in a mustard of white.

A slip, or thermal vest and woolly tights.
snood ?

Thanks for the quick responses! It's for the races, but in the least formal part so not too fancy!

Leather jacket, suede jacket, nice chunky knitted cardi or long black one

Races outside I would just wear a coat if you have something that isn't a pack-a-Mac?

Polo neck underneath. Tights and boots.

Leather jacket. Vest underneath.

Assuming you're not moving much and the 2 hours is into the evening...
Long sleeved base layer, cycling shorts/ chub-rub shorts.
Long Coat.
I'd take my gloves too tbh.

We were sitting out at the cricket in similar temps last night & it was cold. You can always take a layer off!

I'd opt for a blazer and scarf, or a coat.

I'd wear a poncho

Long trench coat

Thermals underneath and a long black cardigan

A trench coat.

Tights and a long gilet with knee boots

Missed that you didn't want a biker, sorry. In that case, maybe a cardigan on top or a thermal underneath, plus a bright (unfastened) trench coat and a scarf.

And whether you're just sitting or moving around will make a difference, as somebody said below. If just sitting, you could take a blanket!

M&S do lovely light but warm, long sleeved thermal vests.
