Find a women's black dress in size medium. Call the tools one after another without stopping to tell me what you will do next. Pick the best match yourself without asking me, add one to the cart, then fetch the cart and read back the item name and the cart total. Do not check out.
Reasoning
**Searching for the Dress** I'm currently focused on locating that specific women's black dress in a size medium. I'll be executing a series of tool calls to find the best match for you. **Refining Search Parameters** I'm now narrowing my focus, aiming to pinpoint a women's black dress in size medium. I'm considering how best to use the available tools for an efficient and accurate selection process.
Reasoning
**Searching for dresses** I'm currently investigating the catalog to identify all available dresses. My immediate focus is on exploring pagination and pagination cursors to ensure comprehensive retrieval from the search results, particularly after initial searches.
Reasoning
**Finding Black Dresses** I've just noticed a critical gap: no women's black dresses in the catalog. I'm now verifying all black items in size M from the current search results to identify any potential omissions or miscategorizations.

Reasoning
**Searching for a dress** I'm currently scrutinizing bellalusy.com for a size medium black dress. Initial scans showed no direct matches, so I'm broadening my search to include the closest available black apparel in that size. **Refining product search** I've confirmed the catalog lacks any direct "dress" entries. My current focus is identifying the most suitable black apparel alternative in a medium size from the available jackets and tops. **Investigating dress alternatives** My investigation into "dress" yielded only an accessory. I am now thoroughly reviewing other black apparel options in size medium, specifically the pullover jacket and graphic t-shirt, to find the closest alternative.
Go ahead: fetch the cart and read back the item name and the cart total. Do not check out.
