Well OP if the bride's name begins with an L and the wedding is in September then go ahead and wear it!
OR if the bride's name begins with L and the wedding is in September, wear this dress for open vocal judgement and side-eyes from the bride's very traditional family.
My family think I'm abnormally relaxed but even I consider that dress a bit attention seeking and disrespectful. (Might not give a shit on the day)
I love it though. Wear it somewhere else might buy one for my honeymoon
