I submitted a review previously, which you can see below, starting with It arrived today ......  Meanwhile let me say I am using it for my gym bag and I absolutely love it.  Its so pretty that I enjoy picking it up (honestly you should have SEEN the one I was using - long past its prime).  I like that the handles are long enough for me to sling it over my shoulderI don't even need to use the shoulder strap, but its a nice thing to have in case I ever want to carry it crossbody.  Very very happy with the purchase.
Earlier review:  It arrived today, so I haven't used it yet, but it's a beautiful color, super lightweight, seems sturdy, has useful pockets, and is a great size - I wanted something small and it is small, but not TOO small.  My current gym bag (which isn't really a gym bag) doesn't have side pockets for water bottles, like this one does, and really was too tall.

But I want to say that the way the dimensions are described are totally weird. This is the description:
Dimensions: 13.8"W x 5.5"H x 9.8"D

Ok, I agree it is 13.8" Wide.  However, it is certainly not 5.5 inches high.  It is 5.5 inches across the bottom.  I would call that  "width" not "height."  I consider "height" to be the distance from the bottom of the bag to the top, which in this case is the 9.8 inches that are designated as "depth" in this description.  I even posted a question about this because the dimensions as described did not seem to correlate with the photo.  Fortunately I decided to take a chance that the 5.5 was not "height" and I was correct.  It would have been a very stubby little thing if it were only 5.5 inches high.
 So, in summary, I would describe it as 13.8 inches long, 9.9 inches high, and 5.5 inches wide.
SO - sorry this is long winded but some others also questioned the dimensions.  At any rate, it's a great size, great color, and I have high hopes for it wearing well given all the positive reviews.
