Requesting their swimsuits changed to look like panties/lingerie. I know they can largely pass as them already, but include things you more commonly see on them, like frills, bows, crotch seams, non-tie bra straps etc.
No specific preference for their design or their colors, but have them generally follow the original outlines* and don't use any uncommon colors/designs (no yellow/green/orange or triangular bra cups). Keep Jun's panties side-tie though, and make the strings thinner.
Topless edit and nude filter that might be of help for references:
