Great price to come with being a pretty mummy-to-be

Just bought a topshop shirt dress that cost $71.20.. that i can wear for prob another 2 months...I have been like that. In just 2 weeks, I have already spent $320.60 on 7 tops that will look nice during these 2 months or so, by not making my tummy not too obvious... but prob can't fit into them after that due to various reasons..... Too big an expenditure, but i am still buying...am rationalising it by saying that if i don't buy, i will not have clothes to wear to work at all.. (remember my miserable section 1 of my wardrobe).. and i need to look nice.. :p
With my maternity bottoms i bought at Spring Maternity, I have spent $551.20 within these 2 weeks... OMG.. need to control if not i won't dare to look at my credit card bills next month.
