In a clothes shop, ask Can I try it on? to wear it before buying, How much is it? for the price, and Do you have a bigger size? to find a larger one.
Asking in the shop
Can I try it on? — This looks nice. Can I try it on?
How much is it? — How much is it?
Do you have a bigger size? — Do you have a bigger size?
Try it: Camila: That jacket looks nice. ___ Farid: Of course. The fitting room is over there. Camila wants to wear the jacket before she buys it. Which fits? (Can I try it on? / How much is it? / It's on sale) Answer: Can I try it on? — Can I try it on? asks to wear it before buying, and the reply points to the fitting room. How much is it? asks the price and It's on sale describes the price, so neither one asks to wear it.
Talking about the clothes
To describe clothes, say It fits well when it is the right size, It's too small when it is not big enough, and It's on sale when the price is lower than usual.
It fits well — This coat fits well.
It's too small — This shirt is too small.
It's on sale — It's on sale today.
Try it: Amina: How is that shirt? Diego: ___ I can't even close it. The shirt does not fit Diego because it is not big enough. Which fits? (It's too small. / It fits well. / It's on sale.) Answer: It's too small. — It's too small means it is not big enough, which is why Diego can't close it. It fits well means it is the right size and It's on sale is about the price, so neither one explains a shirt that won't close.
Paying and taking things back
The words you need at the counter. The price is how much a thing costs. You can pay with credit cards or cash, and you keep the receipt — the small paper proving you paid. With that receipt you can return something you do not want. The fitting room is where you try clothes on, and a tailor can shorten trousers that are too long.
price — What's the price of these jeans?
credit cards — Do you accept credit cards?
receipt — Can I get a receipt, please?
return — I would like to return this shirt.
fitting room — The fitting room is over there.
shorten — Can you shorten these pants?
Try it: Camila wants to bring a shirt back to the shop. First she needs the ___ that proves she paid. (receipt / price / fitting room) Answer: receipt — The receipt is the paper that proves you paid, and a shop asks for it before taking something back. The price is only how much it cost, and the fitting room is where you try clothes on.
Try it: The pants are too long. Camila asks the tailor to ___ them. (shorten / return / price) Answer: shorten — Shorten means make something shorter, which is what long pants need. Return means take it back to the shop and price is how much it costs, so neither one changes the length.
