Help needed with mystery 'Do Not Remove' label

[jaamy]

I ordered several different dresses, from several different retailers for myself and my daughter to try on for an upcoming wedding. Following our trying on session, I found one of those 'Do not remove this label unless you are completely happy with your purchase' labels lying on the floor. Not a clue which dress it belongs to. The tag hasn't been fastened though so would be easy enough to re-attach...if only I knew which dress it was from. Am returning them all and now worried that one might be refused if the correct label isn't on it.
The label is red and triangular and I've only ever seen one like this on a top from Next, but I didn't order anything from Next! Need help please to help me identify possible label-dress match. Dresses involved are from: Coast, River Island and Chi Chi (all via Very) and Quiz (via Dorothy Perkins). Also ordered various shoes and bags via Debenhams but can't see such a label belonging to accessories. Has anyone noticed one of these labels on anything they have purchased form these outlets? Thank you muchly.
Logically, would think it would belong to Coast dress as it is most expensive but I haven't seen one of these labels on a Coast dress before.

It's a Very tag. It'll be from one of the ones from there. Probably the most expensive although that doesn't always follow...

Chi chi definitely use those tags. I had one on my bridesmaid dress. I'd think it's the Chi Chi one

Thanks Anchor - narrows it down a bit.
Pixie - There were 2 Chi Chi dresses...will go and check if one of them has the same tag. Thanks.
