The Caribbean blue is a nice color, but I see no benefit in being reversible, as the color is the same on both sides. I'm 5'5, weigh 128 lbs. and ordered the small (my usual size is medium, I ordered the small as they are unisex). It's important to remember these are UNISEX, so will fit both men and women who wear a size small, medium, etc. These are too big for me; I managed to shrink them a little by washing in hot water, but not by much. You can cinch the waist to get a reasonable fit, but the legs are still baggy. The length seems to be about right. If you want loose pants, these may work for you. Women will want to order 1-2 sizes down to get a closer fit. I wouldn't order these again, unless they made smaller sizes with a slimmer cut through the legs .For men who wear a size small, they would probably be OK.
