Hi Rungrat ,
We’re sending you a quick email to confirm all the details of your order.
We're really quick at getting your parcel ready to send out to you - once you click to confirm your order we aim to have it picked, packed and processed swiftly. This means we're not able to make any changes to it, including shipping address, items' colors and sizes or removing anything from your order.
You can still cancel your order after placing it. You have up to 15 minutes for a Next Day shipping option, up to 30 minutes if you've selected an Express or Evening Next Day Shipping or 1 hour after placing it for Standard Shipping.
Just log into your ASOS account where you can view the last 5 orders placed. This will give you the option to cancel in the timeframe listed above.
