I saw the most goregous dress today in Hobbs. DH actually told me to buy it but it cost £229 (mind you it was reduced from £299!). I didn't dare try it on.
The only occasion I have to wear a dress like that is for a works Xmas Doo which it not that posh a function.
So the question is - Would you have bought it if your DH / DP actaully gave it the seal of approval ? ie you didn't have the hide the price tag !
