GuruBlue, thank you very much for telling me about popular clothes in America. What does the word "bill forward" mean?

Can you please tell me if I made any mistakes in describing clothes? I'm typing you the sentences again. Thank you in advance.
1)I don’t like following the latest fashion. I usually buy cheap, loose-fitting clothes.
2)I like wearing trouser suits (or pantsuits), baggy trousers, striped long-sleeved polo sweatshirts (or long-sleeved polo sweatshirts with stripes).
3)I usually buy my clothes at a clothes shop/at a big department store/at a boutique/at the market (where else can you buy clothes in America?) near my house. I have never bought second-hand clothes (?)
4) At the moment I’m wearing a pair of tracksuit (sweatsuit) trousers (or bottoms?) with a checked hooded zip-up (is the adjective order correct?) sweatshirt over it. I’m also wearing a white T-shirt underneath (or under the sweatshirt)
5)I don’t like wearing stilettos (high-heeled shoes) or leather boots.
6)I don’t like wearing turtle-neck jumpers (or sweater) or a skirt and a jacket.
7)I prefer Velcro (?) shoes to lace-up shoes or moccasins (what are slide-on shoes?)
8)Could you tell how to get to the cinema from here?
9)I do (or go) scuba-diving/snorkelling
10)Are the following expressions correct if you want to ask for the way to a certain place: “How can I arrive there? “How can I get ther? /Do you know how to get there? / Do you know how I can get there?/ Do you know the way to get there? Do you know the way to the post-office?
11)Were you having lunch when I rang you (I rang you up, called you up, phoned you ) are they all possible?

The phrase "bill forward" typically refers to a billing arrangement where charges are forwarded to a third party or organization for payment. It means that the bill is sent to someone else to pay instead of the recipient of the service or product.

Now, let's review the sentences you provided:

1) The sentences are correct grammatically. However, instead of saying "loose-fitting clothes," you could say "comfortable, casual clothes."

2) The sentence is correct. Instead of "striped long-sleeved polo sweatshirts," you could say "long-sleeved polo shirts with stripes."

3) The sentence is correct. Instead of saying "clothes shop," you could say "clothing store." Second-hand clothes are commonly referred to as "used clothes" or "thrifted clothes" in the United States.

4) The sentence is correct. Instead of "checked hooded zip-up sweatshirt," you could say "hooded sweatshirt with a check pattern." The adjective order is correct.

5) The sentence is correct.

6) The sentence is correct. Instead of "turtle-neck jumpers," you could say "turtleneck sweaters."

7) The sentence is correct. Slide-on shoes are shoes that you can easily slip on and off, such as sandals or slippers.

8) To ask for directions, you could say, "Could you tell me how to get to the cinema from here?"

9) The sentence is correct. Both "do scuba-diving" and "go scuba-diving" are possible.

10) The following expressions are correct ways to ask for directions: "How can I get there?", "Do you know how to get there?", "Do you know how I can get there?", "Do you know the way to get there?", and "Do you know the way to the post office?"

11) The sentence is correct. "I rang you," "I rang you up," "I called you up," and "I phoned you" are all possible ways to express making a phone call.

The phrase "bill forward" typically refers to a billing cycle in which a customer is billed for future charges or expenses before they have occurred. It is often used in the context of monthly subscriptions or services where the provider requests payment in advance.

Now let's review the sentences you provided and check for any mistakes:

1) No mistakes found. The sentence is correct.

2) The sentence is correct, but you may consider rephrasing "with stripes" as "featuring stripes" for better clarity.

3) The sentence is correct. However, there is no specific mention of where else you can buy clothes in America. Other options could include online shopping or thrift stores for second-hand clothes.

4) The adjective order is correct in the sentence. Instead of "zip-up sweatshirt," it would be more common to say "hooded zip-up sweatshirt."

5) No mistakes found. The sentence is correct.

6) No mistakes found. The sentence is correct.

7) Velcro shoes are a good alternative to lace-up shoes or moccasins. Slide-on shoes refer to footwear that can easily be slipped on without the need for laces, straps, or buckles.

8) To provide directions, you would say, "Could you tell me how to get to the cinema from here?" The word "me" was missing in the original sentence.

9) Both "I do scuba diving" and "I go scuba diving" are correct, but "go scuba diving" is more commonly used.

10) All of the expressions are correct and commonly used to ask for directions. Here are the variations:
- "How can I arrive there?" -> "How can I get there?"
- "Do you know how to get there?"
- "Do you know how I can get there?"
- "Do you know the way to get there?"
- "Do you know the way to the post office?"

11) All the options for "when I rang you" are correct: "I rang you," "I rang you up," "I called you up," and "I phoned you" are all possible in this context.

I hope this helps! Let me know if you have any more questions.
