HavaianasTop Unisex Adult Flip Flops

Is this for men's and women's? the sizing seems to indicate that it is men's: eg. 37-39 BR/US7-8B(M)

If I wear women size 8.5 or 9 what size should I order?

Which size of havaianas is best for someone who fits a size 7 in women's shoes?

Picture color is white, however description says: marine blue, what it’s the real color?
