Just wondering... my new Paddington (medium) came with the side belts buckled at their tightest. Means that I always have to open both zips to be able to reach inside and grab anything. Does everyone keep theirs this way? Are there any reasons to adjust the side buckles? Or any reason why I should leave them that way? (I know, this is like a totally ignoramus question, but what the heck...what is a purseblog for?) Thanks all!
