I didn't realize when ordering this that it wouldn't be lined like the other Squeem's I have bought in the past. I wasn't pleased with that because it added work to an already awkward piece, but it was my fault for not noticing when ordering. However, the slip on liner that came with it is SUPER small. I can't get it on at all and so took an old, slim fitting tank top and cut the top half off so that I could slip it on and then put the Squeem on over it as the one that came with it was intended.
