Personally I think Louise's reason for requesting baggy clothes has always been due to feeling out of shape/fat whatever but she used the 'doing it for my kids and hot Jamie as an excuse.
If she had said the real reason, it would have
(a) drawn attention to her figure immediately which for someone with confidence issues, would just intensify her issues.
(b) seemed disingenuous considering the majority of women would love to have her figure - ok, she may be slightly bigger than she has been but she is still slim. How many people hate hearing slim people moan about how fat they are?
However, I wonder if she has now stated the real reason because she feels more comfortable in the environment, has seen larger women than her dress well and not be embarrassed? Just thinking it might be like when you go on holiday - certainly in my case, before I go, I hate my figure and try and lose weight then once I am there and realise women come in all shapes and sizes, I suddenly don't care what I look like in a bikini/swimsuit.
She used Jamie and the kids as an excuse but it backfired on her so she has now coughed up the real reason.
Whatever it is, she needs to just embrace the lycra and glitter - you only get one chance on SCD!
