I haven't purchased many strapless bras before, but I am enjoying this one. I typically wear a 36C but occasionally I'll find a 38C that fits great too.
I purchased the 38C and it's a touch big. I wore it all day yesterday, but only had to adjust it once. If you're looking for a good support bra this is probably not for you. It's thin and lightweight which is exactly what I wanted. I will be purchasing more of these aoon
