The "th" should be prounced in both cases. It would be a "soft" th sound, as in "mother".
If you don't pronounce the th, you will be saying "mouse" and "close". People will regard your pronunciation as sloppy, but will probably know what you mean from the context.

Can we omit the 'th' sound in normal speech?
2. clothes
(We can omit the 'th' sound in this word, right?)
