I love zaful! I ordered two bikinis from them, the blue one (/low-waisted-padded-scoop-bikini-set-p_*******. Html) & a beige one(/knotted-textured-scoop-bikini-set-p_*******. Html). Both were bought in a size medium according to the sizing chart.
The beige was too small, so zaful refunded me(including shipping) & i still got to keep it! They also gave me the option to resend a size larger free of charge.
The blue one looks gorgeous on me though! The bottoms are the perfect level on cheeky. It's my new favourite bikini!
