Louis vuitton speedy?

Here is my problem I'm thinking about getting a LV speedy but don't know if I should get a speedy 25 or 30. I have looked into it by going on youtube and other sites. Some site have said that the speedy25 is best for small ladies under 5'6" and the speedy30 will look better on taller ladies. speedy25 was my first option but thought it may be too small,but will the speedy 30 look silly with me being 5'2.Please helppppp!!!!! thanks
