1) G2000, stocks the most well priced and good quality stuff,
next in line, you can try Robinson's and John Little. Wing Tai
group holds some warehouse sales occasionally at their factory at
tampines rd near the superbowl at hougang south.
2) Wrinkle free polyester cotton shirts, but I tell you from
experience, it ain't 100% wrinkle free, please iron before you wear
it, otherwise you look really sloppy, like someone who couldn't be
bothered to dress up for the occasion. Very bad.
3) No, it is not fine, your ankles are left exposed when you sit
down. Just go and try it and look at yourself, you'll find yourself
looking awfully silly. Please wear dark coloured socks with dark
coloured leather shoes, same goes if the shoe is white. Its
comfortable yes, now imagine someone who wears shorts and socks
with leather shoes. Same as the above, don't make yourself look
sloppy if you want to dress up welll. Especially when it comes to
corporate attire.
