My sister who has always been a size 10 has put a bit of weight on recently and is now a size 14, although I know this isn?t big, she feels a little uncomfortable with it and is stuck for what to wear for her Christmas work party and also New Years Eve party. Both are relatively relaxed occasions so something casual with a hint of smart would suit. Any suggestions for her? She?s a bit shorter than me so I?d say about 5ft 6 and a size 14. She wants something that will ideally flatter her and hide her belly a bit.
