Thank you, wonderful Mumsnet.
I've had so much fun with this and have loved the honest opinions. I identify with clothes way too much and this has been brilliant for getting a bit of thought injected into my reactivity and event stress/purchase relief impulse,
I will not, for the record, be buying the dress, but will wear something I bought years ago but have never really made the most of - a dress from Haute Hippie acquired on the Outnet - swirly green-purply-grey - with an old (label on!) pale pink linen Jigsaw jacket.
Thank you for steering me away from the unnecessary purchase .
