サイズが大きかったので返品をお願いします。って英語でなんて言うの？

'Could I possibly...'' and ''Is it all right if I...?'' are common polite phrases used to make requests. So if you would like someone to do something for you or you are asking them for permission to do something, then you can use these phrases. I'd (I would) is generally more polite to use than ''I want''.

When we try clothes on at the store, they may feel like they fit at that moment. But when you go home, they don't fit anymore. If you can no longer wear the clothes then you must return them. If you have to return them just go to the return desk and say politely, " Hi I tried on these clothes but they did not fit, may I return them please?" They should either give you your money back or allow you to change and get a different size for the same price. As long as you bring the clothes back before 30 days have passed, you will be able to return them.

"Excuse me, Please can I return this. The size is too big." "Excuse me" will get the persons attention. "Please, can I return this. The size is too big." This politely explains to the person that you would like to return the item of clothing because the item is too big for you to wear. "Excuse me, I would like to swap this item, this size is too big." This is another polite way of getting their attention and asking them if you are able to swap the item of clothes to a smaller size.

Depending on the return policy of the store they can either refund you your money or allow you to exchange it for something. They may also want you to provide the receipt as poof of purchase. Whenever you buy something always keep the receipt and throw it away when you are very sure that you want the item.

Some shops do not accept returns of some goods once a person has bought them and taken them home. Usually, clothes may be returned, or exchanged for the right sizes. However, if you find yourself in such a situation whereby you have to return clothes because they are too big for you, you have to politely ask the store staff if they can allow you to return them. So, you may ask: May I please return these clothes since they are too big for me? or Will you please allow me to return these shoes as the size is too big for me?

Depending on the individuals stores return policies, most of the time we can return goods (with tags still attached) if the size does not suit. We can simply return them to the store with the receipt, explain why and ask politely "Excuse me, could I please return this top as the size is too small".

If you purchase items that do not fit you should either be able to get a refund or an exchange. Refund means you get your money back. Exchange means that you can swap it for another item that does fit (for the same price). Most stores will refund or exchange if clothes are returned as new and you have the receipt.
