I'm 5 ft half inch, lol, and 105lbs, but people say I look around 5"4, if that makes a difference in this thread about height and proportion. I carry a damier 30 and I have plenty of room to spare in that bag. I know a 25 would suit my carrying needs but prefer the look of the 30's. I feel the 25 is too young for me, I'm in my early 30's but think of girls in their teens and 20's when I look at the speedy 25. Also I love that Jessica Simpson and Katherine McPhee, wear a 30 as I really admire their style as lame as that sounds that I like carrying the same size they do, lol.
