i am pretty petite (five 2 and "small boned" ) if i was taller, even just a couple more inches i would be more than happy being a 10 - 12 as proportionally i would still look very slim. but i am a shortarse little and every extra Lb shows :/
and would probably only need to lose 5 - 10lbs to get to this size (am currently 8 stone 2, and a dress size 8 - 10 )
i have been a size 6 before in my teens and early 20s and after i had dc1 and became single and basically couldn't afford to eat and felt great at that size, like i could wear anything
i just think very slim women look great in anything
....and thats just MY opinion btw so i dont want to offend anyone
