Information of Women's suits and thickness

[Sprinter51m]

Morning. I am new to diving and want to have my own suit that fits decent. I have been surfing through the posts for women's suits and haven't noticed any new conversations since 2011 or so about good/better/best full suits for women with larger chests and about 5'6". I have tried the BARE suits when we were being certified, but they were usually too long in order for them to fit me on top. I am looking for opinions on what is the most comfortable suit that is easy to put on. As far as mm, I am not sure if I should go with a 3 or 5. We are diving in Myrtle Beach in September and then in Belize in February. Can I use the same for both? I would need a 7 for diving locally (in WI) but for that, I will stick to renting.

Thanks for any information.....

Jamie
