“Sizing is not correct on STP”

“Bought this for my first triathlon in 4 weeks. I haven't used the product but I wanted to let others know that the sizing is off on this website. You must go to the orca website and look at the sizing based on your measurements. I am normally a US 10-12 and I ordered a UK 12 and UK 14. The 14 fits now but as I lose my baby belly I think I will move into the 12. Also bought the matching shorts and I purchased a UK 14 (which says on the tag US 8). Aren't they so sweet making the sizes small so I can say I wear an 8 :) Like I said, I normally wear US 10-12 and the UK 14 fit perfect. Check your measurements on Orcas website or you may choose the wrong size.”
