Yeah I know, I guess that's the downfall with net shopping cause you can't try it on but some things on Asos can be so cheap, it's worth it! I bought my bikinis for like $35 and was not too sure about my sizing since my bra size varies with different bras, but luckily I got the right size! Just go by your cup size with Asos bikinis orr I can measure you bbygurl.
