Teacher: Now, understand the problem? Solve this instance: [header] How to shop for a wedding dress [title] Decide when to shop. [step] There's no time too early to start looking, but there is a time that's too late. Depending on where you get your dress, it could take several months for your dress to be ordered and shipped. <sep> (A) From then, you'll need several weeks for your seamstress to make alterations. You should start shopping about 9 months before your wedding, but preferably sooner. (B) If you aren't sure about the exact times, make a list. [substeps] If you're unable to visit the store and the dress is not shipped out in advance, sit down and plan a shopping trip around that time. (C) If you get your dress shipped at the last minute, that's even worse. Some wedding dress designers are willing to let you pick the bride/groom's dress, so don't make this a trial run. (D) One such example would be march 1st, and the exact timing might vary slightly by weather. In situations where you normally buy on cold winter days, however, it may be best to shop before your wedding day or if possible if it's crowded.
