Its a posh lunch then going on to an afternoon tea so more relaxed. I have no idea what to wear.
Am a 16 ( was so much bigger in the past it was tents only!) about 5ft8 with flabby tummy .
In an idea world would like to wear it again so not OTT posh. No maxi dresses ( as they are mega tripping up material for me) also tops of arms ares still a bit untoned.Also pretty adverse to floral ...
I have looked at Debenehams, Next and M&S ( as I am overseas and can get it posted to the UK)Boden ( not me) and not really seen anything that grabs me ....
Just thought would ask if anybody has any suggestions on wher eelse I could look ....Or if you have any suggestions on outfits. Ta muchly in advance!
