Extremly disgusted

Im so so upset im failing to even type. I bot a dress on the 24th of december. Wore it on the 25th. Today as i was washing it i noticed to tag on the neckline says size 32 nd the inside tag says size 36. What sort of nonsense is this. Clearly i was a clown wen i wore this dress cz i was putting on a dress 2 sizes bigger than me. Iys so so embarrasing to think of it nw . im sure people were laughing at me at the function that i had on a very big dress. This is just so un acceptable. Deal with this now cz im really not happy.
