The reason the Dolce and Gabbana suits are more expensive are because they're much nicer - they're canvassed, I checked I was tempted but the cloth looked too much like something I already have ('Super Worsted' Oxxford) though the cut is obviously very different. If the Dolce fits you well, it'd be a better buy than the 200 pound suit with alterations.
I do like the Dolce and Gabbana one, altho I am not so sure about the colour of the DG suit. It looks kind of a dark cloudy dirty kind of blue to me, not sure if I could pull it off. Altho from what you said, the quality seems to be not bad at all. I might give it other try on to see. They do have a few of them in stock so I guess they won't be gone so quickly.
As regard to the quality of the fabric used on these suits, could you teach me how to tell if the quality is good/bad? I've read a bit about super 100s, 120s..etc but surely, it must be hard if not impossible for someone clueless like myself to identify the exact quality of wool?
I was looking at the TaT thread and its website. I do really like the silhouette (Not sure I used the word correctly LOL) of their one button suit I can imagine it would look quite flattering for my body shape, altho the trousers could possibly be too tight from some of the pictures I saw of other SFers wearing the suit. Feedback from other people are mostly brilliant as well. Furthermore, the price is spot on to my budget as well (US$400 for SFers inc. shipping). However, the only thing I'm concern is that the one-button style might be not so suitable for graduation, work, interview and more formal occasions? Well...nevertheless its definitely something worth considering for me.
