Changing room mirrors

[Bearcat]

Do you think that the mirrors in shop changing rooms ( M&S) make you look slimmer than you really are?
I have lost 3 stone in the last 18 months, and am quite pleased with the way I look in my clothes now, but seeing my back view in the mirror this morning i think I looked slimmer than I probably really look from behind.
I would be pleased to look like that, but what do you all think???

I am sure some of the mirrors make you look fatter and others thinner.

i find m and s mirrors the scariest as you see yourself from every angle M and Co and Wallis mirrors definately make you look slimmer
