I did some digging since OP didn't respond with links to anyone.
shoulders & arms: https://www.amazon.com/gp/product/B07GKK9BMT/ref=ox\_sc\_act\_image\_1?smid=AKENEG806CQ5Z&psc=1
Top 1(OP said she used a sports bra filled with socks, so black sports bra):

Top 2(seems to be a not smooth tube top, this is closest I could find): https://www.amazon.com/gp/product/B07GWYS83Q/ref=ox\_sc\_act\_image\_1?smid=A2YNIV6CLV9PUK&psc=1
corset: https://www.amazon.com/gp/product/B07XBPXN15/ref=ox\_sc\_saved\_image\_4?smid=A36ST3G4H0VVEC&th=1&psc=1
Shorts/hips (I'm not sure. In the pictures it looks a bit longer, but this is the closest I could find): https://www.amazon.com/gp/product/B078VQTX5D/ref=ox\_sc\_act\_image\_1?smid=A3JMZ4EL52GCAP&psc=1
skirt (not what OP originally got since she said the slits were cut, but "double slit maxi skirt/dress" will pull up the same design): https://www.amazon.com/gp/product/B01BFXCKK8/ref=ox\_sc\_act\_image\_1?smid=AXAINU30TOR2R&psc=1
fishnets (prob the most generic piece): https://www.amazon.com/gp/product/B07NV4JGTG/ref=ox\_sc\_act\_image\_1?smid=A3S7HD0GWIJUH7&psc=1
stockings (IDK, this seems the closest): https://www.amazon.com/gp/product/B003S2QKVU/ref=ox\_sc\_act\_image\_1?smid=ATVPDKIKX0DER&psc=1
garters: https://www.amazon.com/gp/product/B093WJB99T/ref=ox\_sc\_act\_image\_1?smid=AUKX0J48DAJTG&psc=1
bracelets (can just search "spike bracelet" and choose from there if long spikes are iffy for you): https://www.amazon.com/gp/product/B07B2PRKT4/ref=ox\_sc\_act\_image\_1?smid=A36XJEO0NW17R2&psc=1
Choker (in the pic the chain links seem bigger than what this has but this is the closest I could find): https://www.amazon.com/gp/product/B07LFVJH6D/ref=ox\_sc\_act\_image\_1?smid=A54G7OLD0YLLI&psc=1
