Note: most of the stores mentioned, while they also sell men's underwear, are geared primarily towards women. Depending on your place of work and your/their personal sense of propriety, many of the sites may also be considered NSFW. Just don't say I didn't tell you :-) .

Possibly one of the more expensive items of clothing many of us women wear at any given time is our bra. This is especially true if you're the well-endowed type, are pregnant or nursing, or have had a mastectomy. Such bras purchased locally can each cost several hundred Shekels.
Women who need shapewear have a similar problem. Good quality shapewear, which, in my humble opinion, is the only type worth wearing, can also run you several hundred Shekels bought locally. Or you could take your chances with an as-seen-on-TV bodyshaper via
Groupon.
Fortunately, there are other excellent options with reasonable, fast shipping from abroad, so you shouldn't feel you need to compromise on quality at the expense of a decently-priced item.
