Can anyone help me & my sister find this bridesmaid dress for her wedding??

[CloudOfStarlings]

hello!
My sister is getting married in August.. I am a bridesmaid. She wants the 3 bridesmaids in different coloured one shoulder maxi dresses.. the other two already have a coral one and a grey one and we're trying to get me a mint-coloured one.
We found this H&M dress which we love but it's sold out in my size (10) we bought a 12 on ebay hoping it would fit anyway, but it was way too big.. so now we're waiting for a 10 to come up again on ebay but the wedding is approaching fast

Any ideas anyone?? We really love this dress and it needs to be this colour (and one shoulder, as the other two dresses are) but short of calling every H & M store in the country or just hoping it comes up on ebay I'm not sure what to do!

It's gone for me too now. Was available earlier.
I think i'd tweet them, that always seems to get quick responses from companies.

I would still pop and see a dress maker/ tailor to see about altering the size 12 , bearing in mind how intricate bridal gowns can be and they are regularly altered, I wouldn't imagine that it would be a problem?

So you think more 10s became available and then sold out? Or is this just a site glitch? I'm so confused.

Thanks all, will look at a dressmaker. And yes great idea about tweeting thanks.

Sorted! A 10 came up on ebay and the seller agreed to a Buy it Now price.. thanks all so much for your help; when I told her all the suggestions on here she was quite touched you'd all taken the time to respond so thanks :)

Great news. I'm sure you'll all look fab.

Result! Great news
