Glad to help! Here is what Sharon said about sizing in tops:
For Kos-USA:
kos-usa tops Tankini's run bigger. Sm/32-34C if they (34C)like their tops tight. ; med. 34B-36C ;large 36C-38B.
For Oh My Bod:
tops: small (32-34b,c); med. (34c-36b); large(36C-38B)
The criss cross top-Is a great supportive top. small /med. sized like small ; med/large is like the med and large; large/exlarge (36D-38C)(custom order)
And I forgot something for the pants sizing for Oh My Bod:
small (2-5) up to 5 foot 4 inches or so. med/large(6-12)
"Now with both of these companies, they are using very strechy fabric. Kos-usa---tactel/lycra, and oh my bod uses ---supplex/lycra. both great fabric, So you want to go with how comfortable the size will fit with you. Some women like their cloths tight and others will like the cloths more loose. That is the best way to judge it, or they can always e-mail me or call me."
I think now you have altogether the total email from her, just edited a bit so you can make sense of it. Sharon will be more than happy to answer any further questions on sizing. She answered my email very quickly (although I understand she is on vacation for a week now)
Happy Shopping!
