So I've lost around forty pounds over the last couple of year and have about 15 more to go before I get to my "ideal weight". I am also desperate for some new clothes, new trousers in particular. I've been doing the cheap department store thing the last couple of times (no use spending good money when the plan is for them not to fit for that long) but I am wondering if I can "safely" buy nice trousers now and be able to have them altered down the line when the last few pounds come off. How much can a tailor reasonably take in on a pair of trousers?
