Ah you read my mind! My baby is almost 5 months old and I would love to see her tackle the post baby body topic by visiting a personal stylist. Would be great exposure for the stylist (not suggesting she shouldn't still pay) and she would come away with clothes that actually suit her. Not that much effort required on her part surely? Instead she just moans constantly that she is not the same as before and has nothing to wear.
Saying that, your clothing also has to suit your personality, not just your body i.e. if you're a super shy person you are probably not going to suit lots of dramatic, statement styles that cause everyone to look at you. Not sure what style suits a mood hoover?!
