V necked sleeveless jumpsuit - how to style it

[AlternativelyWired]

I'm in love with my new Hush jumpsuit. I need a top under it as it's freezing out there and I like to be covered. I've got a long sleeved linen top but it's round necked. I'm not sure it looks right. I'm not too fussed about quirky but I don't want to look daft.

I found this at John Lewis & Partners. What do you think?  https://www.johnlewis.com/hush-jersey-v-neck-jumpsuit/khaki/p5437722?tmad=c&tmcampid=7&sshare=jlappioss_Y29tLmFwcGxlLlVJS2l0LmFjdGl2aXR5LkNvcHlUb1Bhc3RlYm9hcmQ=

I have it in black.
