Took my daughter to South Coast Plaza today with the intention of stopping by LV and picking out a Speedy - I thought it was going to be a difficult decision - picking the right size and I stewed over it all the way down this morning. A week ago I asked for all your advice and of course, you all were right - it was the 30 all the way! Once I was up to the counter, I didn't even consider the 25. Once I got home I emptied my purse into it and it is so full that there is very little sag! I thought 25 was cute, and looked good on my 9 year old. However, not that I am in any way large, but the 25 looked like a toy bag on me. The 30 is perfect! Thanks for advice!
