Bridesmaid dress dilemma

In my engagement bubble I made some decisions and agreed to a few things I’m now regretting, which I'm now having to work out how to deal with. One of which is the ‘bridesmaid’ dresses. I found this dress (pictured) from Coast and decided to get it, without having chosen my own dress or deciding on anything else! I do still like them, but since buying them I’ve changed my mind on so much and now everything's much more relaxed, so I don’t think this dress is really going to go with what I have in mind.

So I’m left with two size 12 dresses, a bill for £375 (the dresses were £125 each, but I had to send one back, which got lost in the post so I couldn’t get my money back!) and I’m still no closer to deciding what to do about it. I've got a lot of thinking to do. xx
