Clothing specific for action figures is scarce, limited in subjects and often very expensive.
There is an alternative though, a doll that started collecting a wardrobe about 61 years ago that no real woman could ever match : Millicent Roberts, aka Barbie.
She was followed by many other such dolls, the closest considering wardrobe contents being probably Sindy from the UK.
Do you want more "manly" stuff ? Then there is GI Joe or Action Man.
There are limits of course. Most female clothing will only fit the smaller TBleague figures PLMB2018-S24A / S25B or even the very small PLMB2018-S26A / S27B. And probably the new PHMB2019-S34 / S35 too. EDIT : NO THEY DON'T FIT THE NORMAL SIZED S34-S35
Kenner dolls or GI JOE clothing in general should fit taller TBLeague figures.
This thread is about showing Phicen/Tbleague or other seamless figures in that clothing and with those accessories.
From time to time I will post my "theme scenes" here, it's up to everyone else to fill the gaps.
Final warning : consider this thread NSFW. If your boss (at work or at home) doesn't mind you watching pictures of dolls, maybe (s)he will mind you watching pictures of dolls clothed (more or less) in sheer clothing.
