Sul sul! Here are some default replacements for most swimsuits available for TF-EF sims. The only one I didn't include was the YF clone since I was struggling to get it working for some reason.

tfbodyswimwear: All of the following are texture replacements only, and use the base game mesh (if you have any mesh defaults for tfbodyswimwear, it will replace the mesh on these ones!). All should be Base Game Compatible, townified, with barefoot shoe sounds. Diving: @deedee-sims 4t2 EP07 Swim Bikini Leaf // Tankini: @deedee-sims' 4t2 trillyke Mojito // CASIE/Flower/Paisley: @microscotch 4t2 Trillyke Flower // Bikini: @deedee-sims 4t2 Swim Bikini Halter // Single: @deedee-sims 4t2 trillyke Drippin' ]

yfbodyswimwear replaced with @microscotch's 4t2 Conversion of Trillyke's Flower Swimsuit, using @platinumaspiration's mesh (retro cut). Categorized as swimwear only, unhidden, townified, and enbaled for AF/EF. It requires The Sims 2: University in order to work.

afbodyswimwear + cleavage: CASIE/Flower replaced with @pop-sims' 4t2 Boschiana Vcay Bikini. Enabled for YF, swimwear only, barefoot, unhidden & townified. // Single replaced with @platinumaspiration's 4t2 EA SP44 Retro Cut Swimsuit. Enabled for YF/EF, swimwear only, barefoot. All other parts of afbodyswimwear use the same mesh as this one! // Diving replaced with @deedee-sims's 4t2 EP07 Swim Bikini Leaf. Enabled for YF/EF, swimwear only, barefoot // Bikini replaced with @platinumaspiration's 4t2 EA SP44 Spaghetti Bikini. Enabled for YF/EF, swimwear only, barefoot. This is the default that includes the hidden "cleavage" (classicblackbikini). // Tankini replaced with @deedee-sims' 4t2 Trillyke Mojito Swimsuit. Enabled for YF, swimwear only, barefoot.

afbodywetsuit & afbodyswimwearsporty: replaced with SkittlesSims 4t2 EP07 Wetsuit. Enabled for YF/EF. Unhidden, but not townified out of personal preference. Swimwear only except for the unhidden career version, which is enabled for swimwear and everyday to hopefully not mess up with any game mechanics (I am a noob at this game still, so lmk if there's any issues with changing the category here). Barefoot shoe sounds. It requires The Sims 2: FreeTime in order to work.

efbodyswimwear replaced with @lucilla-sims' 4t2 Swim Retro and @deedee-sims' Flutter Swimsuit (+pink texture) with @kooli-sims recolours. I used the AF mesh for this one, so its YF/AF enabled. It also includes the CASIE and EP7 elder swimsuits, unhidden, townified, swimwear only, barefoot shoe sounds.
