Translation:In my opinion this dress is not beautiful.
Nope, they're the same thing. The -ce version doesn't work for the 3rd person, though, so you actually have to use the -e göre form for "he/she/they".
Bence = Bana göre
Sence = Sana göre
Bizce = Bize göre
Sizce = Size göre
Note that "onca" and "onlarca" exist, but they mean "so many" and "tens of…" respectively.
Good question! If you say "a dress," you mean a woman's one-piece garment. "She wanted to wear a dress, but it was too cold outside." "Clothes" refers to garments in general. "Will your clothes fit in that small suitcase?" Look up "Ladies dresses" on a store's website to see examples. Unfortunately for learners of English, there is another meaning of "dress." The word is occasionally used to describe what you should wear (how you dress) for a gathering. And invitation might say, "You are invited to a reception honoring the president of the company. Dress is semi-formal." This means men and women should dress in good clothes--men in business suits and women in nice dresses. "You are invited to a bon voyage party for Tom. Dress is casual." The invitees do not need to dress fancy! Note that in those examples, there is no article "the" or "a" before "dress." When you are referring to the ladies' garment, you say "a dress" or "the dress."
