Here are some natural replies you could use, depending on how formal you want to be. Each version goes with the friend’s line “That sweater is too big for you.”
Option 1 — casual
Friend: That sweater is too big for you.
You: Yeah, you’re right. It is a bit big. I’m going to return it. I’ve got the receipt.
Option 2 — straightforward
Friend: That sweater is too big for you.
You: You’re right. I’ll take it back today and see if I can exchange it for a smaller size or get a refund. I have the receipt.
Option 3 — with a store clerk
Friend: That sweater is too big for you.
You: Hi, I’d like to return this sweater. It’s too big for me. I have the receipt. Could I exchange it for a medium or get a refund?
Option 4 — short and casual
Friend: That sweater is too big for you.
You: True. I’ll take it back. I’ve got the receipt, so I’ll try an exchange.
Option 5 — size-focused
Friend: That sweater is too big for you.
You: I know. I need a medium. If they don’t have it, I’ll ask for a refund.
Tips for the return
- Mention the receipt early: “I have the receipt.”
- Ask about options: “exchange for a smaller size or refund?”
- Be clear about condition if needed: “It’s unworn/with tags,” depending on policy.
- If you’re talking to a cashier, you can add: “What’s the return policy on this item?”
If you want, I can tailor a single best version to your style (formal, casual, with a specific store’s policy).
