Dear Godfrey, Now you're making me blush. I made the mistakes and I should own up to it. My excuse is "fast fingers", I should have gone over the post before sending it out. Thanks again for your kind comment.

No offence:

I'll show you where THEY are in the store.
B: Do you think this pair LOOKS good on me? ~ "this pair" 是 singular

It is more common to say:~
B: Let me try ON another pair and see how they look.
