These are my opinions and mine alone. No, I'm not a pearl clutching old bag. Just a dressmaker.
It's a dress that is trying to be pretty but failing.
It's too much.
It's cheap looking.
It's also made of cheap fabric. Zoom in.
I've had a look through the wedding guest dress category on that website.
You need to be very careful. The cut of their dresses is a bit off in general.
They don't even flatter the models for the most part. You run the risk of opening the box to find you are very disappointed.
You suspect the bride probably won't like you showing up in that or you wouldn't be asking. It depends how well you like her, if you're willing to risk upsetting her on her wedding day and possibly losing the friendship.
You can ask here but none of us know her and won't be there to back you up if she goes Tonto on you.
We all fall in love with an item of clothing, occasionally, that we convince ourselves is ideal just because we love the idea of it so much but it ends up more trouble than it's worth.
You just have to weigh up if your feelings matter more than the potential feelings of the bride.
Me, I wouldn't risk upsetting a friend over a dress. I would dress a bit frumpy to please a friend getting married, if that would make her happy.
