I am 5'4", and 125 lbs, and small chested.  My hips are larger than usual for someone my height, so usually have problems finding a good fit.  In addition I needed a shirt that could keep me cool when exercising.  Also, I don't like a compression fit, I prefer a looser fit.  This shirt fits the bill perfectly.  It flares just a little at the hip for my wide hips, and it's of the hi/low construction so my butt is covered in the back. It's not baggy though, and it's attractive! It's wonderfully lightweight, and I also like to wear it for all occasions with our Florida heat. Because it's looser I don't have to worry about them being see through.  I wash, and dry them on low heat in the dryer, and they still look new, and I see no shrinkage. I have noticed a difference between the "vapor lock" (what I have) and some of the other Champion wicking shirts.  The other ones  are a slightly heavier cotton, and don't wick as well.  I have almost every color in the Hi/low vapor lock because I love them so much!
