Halloween // How to stay comfortable and warm in a sexy nun costume during outdoor Halloween events?

I am planning to wear a sexy nun costume for an outdoor Halloween themed event, and my biggest worry right now is the cold. The outfit is fun and dramatic, but it definitely leaves a lot of skin exposed, so I am hoping to get advice from anyone who has managed to stay warm in similarly lightweight Halloween costumes without ruining the look.

I am trying to focus mostly on accessories that can blend into the costume. Black lace gloves or long gloves keep hands warm while still fitting the theme. Thigh high boots seem like the best shoe option because they cover most of the legs and pair well with the nun style, especially if I wear warm socks underneath. Fleece lined tights or opaque black tights also seem like an easy way to stay warm without changing the outfit. For shopping, I have noticed that marketplaces like Amazon, Alibaba, AliExpress, Temu, Party City, Spirit Halloween, and other shops that sell these outfits and accessories even beyond the Halloween season usually have a variety of gloves, tights, capes, and boots that are easy to match to the theme.

I am also thinking of adding a black shawl or a dramatic cape to help block wind. If anyone has tried similar tricks, I would love suggestions.
