This is an Atomic Beauty conversion of Jordan's JC-Shirt and Jeans outfit mod.
YOU NEED TO DOWNLOAD AND install the original first. No way around this.

Please note, my screenshots are taken with the Black Worn jeans texture installed. The standard JC-Shirt and Jeans mod uses a non-worn blue jeans texture, so yours will look different unless you change it. More retextures are available through the original mod's download page, and they will work on this conversion as well.

Let me know if something doesn't work and I'll try to fix it. Unconstructive criticism not welcome.
Directions:

• Download and install the Bodyslide and Outfit Studio utility.
• Download and install the Atomic Beauty body shape.
• Download and install Jordan's JC-Shirt and Jeans
• Download and install this mod (automatically, using NMM, or if manually then extract the file into Fallout 4's Data folder. Overwrite the original mesh when prompted.)
• If you only wish to play with the default Atomic Beauty body shape then stop here and enjoy. If you wish to customize your shape then read on.
• Open the BodySlide utility. The outfits will be within the "AB JC-Shirt and Jeans" group.
• Tweak the sliders to your liking, or use a preset you have already created.
• Craft at the chem bench as described in the original or download the armorsmith patch as linked from the original page and craft at the armorsmith bench.
