It's fine, there's nothing bridal about it- unless it's a very low key 1970s style wedding in the woods.
If it's an average 2021 style wedding it's totally appropriate.
What do you think is 2021 style exactly? 70s, boho and outdoors ticks every wedding trend for 2021 so this dress runs a very real risk of being similar to lots of bride dresses. A 2000 wedding you might have a point.
