Where's the option for "I will spend $150 total on four children this year, but it's only that high because I have to buy a brand new flower girl dress for DD1?"
Because I garage sale (and buy ahead) and put the younger ones in hand-me-downs, I can't imagine spending as much as $100 per child, per year. I mean, I guess I could easily go to Janie and Jack and do that in one shopping trip (!), but our closets are so full that I couldn't justify it to myself. Our total family budget for clothing is $200/year for the kids and me, plus $200 for DH's work clothes.
I will literally buy nothing this year for my younger two because I've saved all the still-decent clothes from my big kids. I recently bought DS a clearance suit coat for summer weddings/church and had to get DD1 a cardigan last month because she had suddenly outgrown all her sweaters and was insisting on running around in sundresses every day--together, less than $30. I just spent $20 at garage sales last week on 13 pairs of pants for DS in the next two sizes and about $3 for a few random tops for DS and DD1 in the next size up. All of DS and DD1's summer clothes from last year still fit them, and they both have a lot of hand-me-downs and garage sale clothes in their next-size-up bins. I'll probably buy everyone new flip-flops at ON this summer, though last summer's still fit everyone right now. I've budgeted $50 for the flower girl dress and have about $50 left over for whatever emergency needs (and basics like socks/underwear) might come up the rest of the year. MIL loves to buy them clothes and dress shoes, so I've learned not to even bother buying them coordinating Christmas/Easter-type outfits unless I really find something I adore, because they will get them from her. I used to splurge on matching Christmas pajamas, but I'm planning to make them this year because it will be too hard to find matching ones in their range of sizes. I buy like-new shoes at garage/consignment sales (I'm very picky about the condition--it's easier to find new girls' shoes than boys' shoes!) but spent $10 for DD1 and $2.50 for DS at Payless on new tennis shoes last fall because I had a gap in my shoe collection.
But I realized last time one of these types of threads came up, I was in the vast minority on these boards!
I'd say it's my hobby to clothe the kids and myself as frugally as possible. It's truly not a burden--I get a big rush out of great deals; I have always hated mall-type shopping. It's also one of the many habits (like cooking from scratch) that allows me to stay home full time with my kids, which is my preference. (I will also say that my kids absolutely don't care if their "new" clothes have tags on them--they are thrilled when I come home from a garage sale with stuff for them or when a friend passes along a bag of hand-me-downs.)
