Lands’ End Paisley Tankini Sz 12 with Underwire

Deep Blue Navy Retro Paisley Tankini Size 12 UPF 50 Chlorine Resistant Underwire with Removable soft cups Covertable and adjustable straps NWT Approximate measurements: Length from pit is 16” Pit to Pit is 16” This is a very Snug Tankini- Unfortunately it didn’t fit me! But it’s super cute- I also bought some shorts - see other listing (listing next) didn’t fit me as well and are not a complete match- but very similar. Also a size 12. I am I guess what you consider “between sizes” and maybe would suggest a size 10 woman would be best?? - :). Or a slim 12.
