"I have a weird skirt and a regular t-shirt."

Translation: عِنْدي تَنّورة غَريبة وَتي شيرْت عادي.

[TalNala]

;D I love this course more and more, I hope at least Seth's new skirt is fairly regular ;) <3

Is "تي شيرت" an MSA word?

Never heard of this word being used in MSA (nor in any dialect),as far as I know T-shirt means "قميص" or "قميص نص كِم" in Arabic

[M_Alrehaily]

No, It's not a MSA word.

[_FiX_]

you are right. even most dialects do not use this word تي شيرت

[tsuj1g1r1]

It is. I use it in both my dialect and MSA.
