Located inside Block Arcade, this shop is best described as a hidden secret. They specialize in shirts and cater to both men & women (upstairs).
The shirts (I can speak for the ladies only) come in a range of colours, patterns and weaves. Fabric and tailoring are both of good quality. Shirts from this boutique will never be see-through, billow at the back or incessantly rise out of your trousers.
NB: they also stock a true size 4 & 6.
Service is excellent. They are friendly, attentive and helpful without being intrusive.
Apart from shirts, they also sells ties, cufflinks, silk/cashmere knits etc
I have listed the average full price for ladies shirts (the men's shirts are fractionally cheaper) but they also do seasonal sales/specials, which offer further value.

Approximate cost: $130-150
