Last-minute bridesmaid dress needed after seamstress disaster, is this suitable?

[Springged]

Help! The wedding is next week and my bridesmaid dress was a disaster. Now urgently trying to find something to wear.

it’s my sister’s wedding and she decided to have the dresses made by a seamstress but mine wasn’t fitted to me (too far away). It was also very late so I received it last week and it doesn’t fit. I knew I would have to get it altered but my seamstress took a look and said there was no chance without completely remaking it from scratch and there wasn’t time or fabric for that.

The bride accepted that but tasked me with finding an alternative and I have a week! Bride said she doesn’t want to help out so I’m on my own.

I’ve ordered some from coast but I’ve tried a few from there and they don’t tend to fit me too well.

I’ve ordered this dress. Is it too young for a 41 year old woman (I was told I look about 30…).

The idea was he dresses would be unique but no time for that now! Do you think someone might turn up wearing the same??

I have sparkly silver heels to go with it.

I wore this as a bridesmaid last year and it was flattering

A quick update! I wore the lace and beads dress I originally posted. Very pretty and comfortable (I sewed up the cleavage a bit) and the bride was very happy which was a relief.
A heads up for anyone looking at dresses from Coast, I’ve had nothing but issues with their returns department. Days upon days of messages to them to try to get the correct label for the return and now there’s a repayment missing that they’re claiming they paid to me. They stop responding as soon as it’s an issue more complicated than a quick check and leave you hanging for days.
Similarly, Debenhams is not great. I did get the refund but no updates that they’d recieved the return. I’m also still waiting for a refund from one of their Marketplace sellers with no updates.
In contrast, Lace and beads was great and Pretty Lavish were very prompt.
