The bride had overdone goth hair and makeup and just assumed everyone would follow the LGBT Christmas Tree Ugly Sweater. When some showed up looking conventionally pretty in an expensive looking put together outfit the bride felt super insecure like the weird girl at the school dance. Dressing edgy and uniquely is often a front of confidence when they are really insecure so they purposefully dress outside the norm, OP came into her cousins bubble of un-conventional dress and popped it.
LGBT Christmas Tree Ugly Sweater, sweater, hoodie, and t-shirt
OP should just explain that she wore this to other peoples weddings, with pics even, and apologize for assuming the bride would be in a conventional gown. OP is not in the wrong but her cousin is clearly immature and LGBT Christmas Tree Ugly Sweater, if she wants a relationship with her OP needs to be the bigger person and apologize for the misunderstanding though bride is 100% at fault for not xommunicating the theme/ real expectations of dresscode. Jeans are not cocktail attire.
Best LGBT Christmas Tree Ugly Sweater
Agree – if the bride thought that her black/purple gothic dress was beautiful and that she would look at her wedding pictures and be happy, then she wouldn’t have thought OP looked better than her. Or that OP looked good at LGBT Christmas Tree Ugly Sweater. The bride would have been mocking OP for showing up looking like the Junior League.
