Which of the options affect the price and which don't? Does Color or Neckline need to alter the price?
Assuming at least two of the options you described will not affect the price, you can configure a product using both "Variations which tell more..." and also "Variants having individual price/weight/stock/SKU" -- each of those allow up to 3 option categories, giving a total of up to 6 options. For the sake of discussion here, I'll presume Color and Neckline do not affect the price, but Size, Sleeves and Rhinestones do.
When you enable Variants, on the next screen you would need to provide a name for up to 3 option categories; e.g., Size, Sleeves and Rhinestones. Below that, you'd need to provide a line for every possible combination of those options, in the order shown there:
E.g., your lines might look something like these (I'm leaving out 2X-6X to keep this brief, but this should be enough to show you the gist):
7XSR,95.00,24,,7XL (+$10),Short,Yes (+$35)
7XLR,100.00,25,,7XL (+$10),Long,Yes (+$35)
You may notice I left the Stock position empty on each line, presuming you would not be using Inventory Control to prevent overselling, and this illustrates what you would do with a position on each line for a setting you're not using -- just leave its spot empty but keep the commas to mark where every position begins and ends. Once you're done setting up Variants, click Next to proceed.
On the next screen, you can configure Variations for options which don't affect the price. This is much simpler, just provide a name for up to 3 options (here we'd be using only 2: Color and Neckline), and below that provide a list of values the buyer can select for each option. Once you're done with Variations, click Next to proceed.
Once you Submit all your settings, you will reach the Button Codes screen. Your Add to Cart button code for this product will automatically include all the menus you'd need to let the buyer select their option preferences. Your View Cart code is unique to you but the same for all your products, so just make sure you have at least one block of View Cart code on every page that has any number of Add to Carts.
