Haha everybody suggests Memo, ako din eh

Depende lang sa budget and body type. I'm a guy and I hardly go to Memo coz their sizes are a bit too big for me kahit small. I'm in corporate attire daily and my closet is stocked with :
Business shirts (long sleeves) :
Marks & Spencer - I get yung tama sa neck ko and have the rest refitted (sa mga nagttrabahong lalaki dapat meron kayong tailor <<sastre>>.
G2000
Par Excellance and
Attitudes slim fit, XS and S (local brands that fit without resizing)
Bench -short sleeves, for Fridays. Try the Stanford Rd line, pero iba dun hindi ko type *** tela, gusutin.
Most of my ties are from Marks & Spencer also.
Pants -
Tyler
F&H
Attitudes and
GQ slim fit
Zara
Chinos from
Topman for casual fridays (skinny carrots or slims in khaki and navy -- reserve the more casual casual ones like yung fitted bottoms for the weekends). Also have 2 skinny slacks I think I bought on discount from them (gray and navy) -- Even Topman skinny business pants are not spray-on skinny sakin ... the spray on skinny jeans are another story though, those I don't buy, I get mine made at Defacto.
Ladies can get away with a lot of brands and can get creative. Get your basics from Memo, Zara, the Black Shop, Maldita and spring for some color from Plains & Prints (sabi mo kase you bought from Flower Collection), even SM brands ... Divi nga marami ka na mabibili o tiangge (my mom is a buy and dispose kind of shopper so she gets those 150 - 300 tops or straight dresses at tiangges, wears them twice then gives em away and buys more ... she loves SM).
