Find a pair of women's black leggings in size medium. Pick the best match yourself without asking me, add one to the cart, then read back the item name and the cart total. Do not check out.
Reasoning
**Finding Black Leggings** I'm currently working through the initial search phase to locate women's black leggings in a medium size. My next step will involve selecting the most suitable option, adding it to the cart, and then confirming the item and total.

Reasoning
**Searching for Leggings** I'm reviewing the search results to identify the most suitable pair of medium-sized black leggings. My next step will be to add the chosen item to the cart and then report back on the item name and the current cart total. **Choosing the Best Leggings** I'm comparing the available black medium leggings. The Training Leggings 2.0 are a popular staple and are in stock at $38.00. I'll proceed with creating a cart using this option.
Reasoning
**Confirming Order Details** I've just confirmed the order details. The specific item added was the Gymshark Training Leggings 2.0 in black, size medium, for a total of $38.00 USD. The line items array correctly reflects this single entry.
I've selected the Gymshark Training Leggings 2.0 - Black in size Medium and added one to your cart.

- Item Name: Gymshark Training Leggings 2.0 - Black (Size: Medium)
