Amoena Hawaii Hipster Bikini Bottom

I live in a cold climate so swimsuits are not available year round. I ordered both the top and bottom of this suit. In just about every name brand I wear a size 4. Sometimes a 4 is too big. Just to play it safe I ordered a size 6. Both pieces are so tiny! This was a clearance item. An 8 is available but based on the 6 I am thinking the 8 will be too small also.
