Is this bag real leather?

No. The outer material is PU, a synthetic leather alternative, with a polyester lining. It looks like leather but will not develop the patina or durability of genuine hide.

Will it hold its shape when full?

The bag is described as soft, so it slouches. It suits light loads like a phone, wallet and keys; heavier items will pull the single strap and distort the body.

Can it be worn crossbody?

It comes with a single shoulder strap only. Unless the strap is long enough to sit across the body, plan on shoulder carry.

It is a shoulder bag with a sandwich outer pocket and polyester lining. It handles daily essentials, but the listing gives no interior pocket count or exact dimensions, so check the size before buying.

Which color should I pick?

The choice is irregular blue and brown or irregular blue and black. Both use the same stitching and soft PU build; the difference is only the colorblock pairing.
