My Dsis has just announced she is getting married in December, very small affair only 20 of us including children. Service and meal will be in the same room within the same building, think old building but newly renovated so hopefully not cold and drafty! There will be the ceremony, lunch and then hopefully just some relaxing in the lounge on the sofas beside the bar 
But . . ..
what the hell do I wear!!!! I am her witness so want to feel special (obviously not bride special) and not let her down.
I am 38, size 16 (although now obv dieting like crazy as 7 wks to go!) and about 5ft 6in. My tummy, bum and thighs have a life of their own so if they could be "disguised/eliminated" that would be even better! Budget probably only £130 ish total inc shoes, bag etc. Also need clothes for my 3 kids but that's a whole different issue
