95% of grammer is correct!

most of them doesnt feel 'smooth'

but i was able to fully understand

what you trying to say ^^

'근데 난 그 옷을 솔직히 싫었어요'

should be

'근데 난 그 옷은 솔직히 싫었어요'

good use of '을' is

난 그 옷을 입었어요.

난 그 옷을 샀어요.

하지만 아 좋아했다고 말했어요

이렇게 거짓말했어.

i have to admit i cannot say this is wrong.

but i would say it doesnt feel right

basically, we dont say like this in korean!

i would say

'하지만 좋다고(좋아보인다고) 거짓말했어요'

not like english ^.^
