Great.  The sleeves are just the right length.  I didn't really want a long-sleeve top, as I think my daughter wouldn't find that comfortable (plus would be too hot in mid summer).  This is short-sleeve, but provides a little more UV coverage of the arm than some other short-sleeve rashguards.  Nice durability, too.  Last summer had a size 3 that I bought used; we wore it a lot, and it still looked great at the end of the summer.  Just bought a size 4 for this summer.
