I'm not really a SRD expert (or fashion one come to think of it!) but just had a browse round the shops and was v impressed with the selection of dresses in Benetton - in terms of style, price and colours. Would never have thought of looking in there before now. Of course their website is pants so I can't do any links to the ones I saw but they have a nice black tunic style linen dress with a scoop neck, slightly puffed sleeves and an elasticated drawstring drop waist so it didnt look too baggy like some tunic style dresses. Also did it in white.
Not a school run dress but they also had a fab black silk dress with a high scoop neck and no sleeves with 2 large cream flowers on which would be great for a wedding and perfect for hiding lumps and bumps as it was fitted over boobs and they just kinda hung down to the knee - but in a v flattering way!
Dam you Benetton website!
Any other suggestions for all SRD seekers?!
